feat: add config profiles data model and migrations

- Add ConfigProfile model with user ownership, name, description
- Add ConfigInclude model for ordered profile self-references
- Add ConfigMount model for mount/file definitions
- Add selected_profile_id to ToolInstance for per-instance profile selection
- Add default profile properties to UserConfig JSONB config
- Create Alembic migration 0013 for new tables and columns
- Register new models in models/__init__.py
- Mark config_folders.is_active as deprecated
- Add migration metadata test

Quality gates: syntax check passed (all files parse successfully)
OpenSpec: add-config-profiles task 1.1

+## Context
+
+The current system uses `config_folders` with a flat `files` JSONB and an `is_active` flag for auto-mounting at tool launch time. This design is inflexible: only one folder can be active, there's no ordering of includes, no explicit per-tool-instance selection, and mount definitions are mixed with file contents in a single blob.
+
+## Goals / Non-Goals
+
+**Goals:**
+- Provide structured config profiles with named collections of mounts and includes
+- Support ordered include lists so profiles can reference other profiles in sequence
+- Allow per-tool-instance profile selection with fallback to user/tool-type defaults
+- Remove implicit auto-mounting behavior at launch time
+- Maintain backward compatibility for existing `config_folders` data during migration
+
+**Non-Goals:**
+- Frontend UI for profile management (separate change)
+- Real-time profile switching on running instances
+- Profile versioning or history
+
+## Decisions
+
+### 1. New `config_profiles` table replaces the semantic role of `config_folders`
+- Rationale: A profile is a higher-level concept than a folder; it includes mounts, includes, and metadata
+- `config_folders` remains for data migration but is no longer used for auto-mounting
+
+### 2. `config_includes` provides ordered many-to-many self-reference on `config_profiles`
+- Rationale: Profiles need to include other profiles (e.g., a "base" profile included by "project-specific")
+- `order_index` column controls application order
+
+### 3. `config_mounts` stores individual mount/file entries
+- Rationale: Normalizing mounts allows querying, ordering, and validation per mount
+- Each mount has a `mount_path`, optional `content` text, and optional `source_profile_id` for transitive includes
+
+### 4. Default profile stored on `user_configs.config` JSONB
+- Rationale: Avoids schema changes to `users`; the existing `user_configs` table already stores per-user JSON
+- Key: `default_profile_id` (global default) and `default_profiles` map for per-tool-type defaults
+
+### 5. `tool_instances.selected_profile_id` for explicit selection
+- Rationale: Clear, direct foreign key; nullable to allow fallback to defaults
+- Null means "use default resolution"
+
+## Risks / Trade-offs
+
+- [Risk] Existing `config_folders` data becomes orphaned if not migrated → Mitigation: keep table, stop auto-mount behavior only
+- [Risk] Profile include cycles could cause infinite loops → Mitigation: validate at write time, detect cycles in include graph
+- [Risk] Multiple includes with overlapping mount paths → Mitigation: last-include-wins based on order_index

+## Why
+
+The current `config_folders` table provides basic file mounting but lacks structured profile management, ordering, and per-tool-instance selection. We need a proper config profile system that supports ordered includes, mount/file definitions, default selection, and explicit profile assignment per tool instance.
+
+## What Changes
+
+- Add `ConfigProfile` model to replace the legacy `config_folders` concept with structured profiles
+- Add `ConfigInclude` model for ordered include lists within profiles
+- Add `ConfigMount` model for mount/file definitions (replacing the flat `files` JSONB on `config_folders`)
+- Add default profile selection per user and tool type
+- Add `selected_profile_id` to `ToolInstance` for per-instance profile selection
+- Remove launch-time reliance on legacy active config folder auto-mounting (mark `config_folders.is_active` as deprecated, stop auto-mounting at launch)
+- Create database migrations for all new tables
+- **BREAKING**: Legacy `config_folders` auto-mounting behavior will be removed; tool instances must explicitly select a profile

+## Context
+
+Currently, tool instances are exposed via an API proxy endpoint that forwards requests from `/instances/{id}/proxy/` to the internal Docker container. This creates latency, adds load to the API service, and doesn't support WebSocket features well. Cloudflare Tunnel offers a better architecture where each instance gets its own HTTPS subdomain.
+
+## Goals / Non-Goals
+
+**Goals:**
+- Each running tool instance gets a unique public HTTPS subdomain
+- No manual DNS or reverse proxy configuration per instance
+- Automatic cleanup when instances are stopped or deleted
+- Support for WebSocket and real-time features (code-server terminal, jupyter kernels)
+- Minimal latency compared to API proxy approach
+
+**Non-Goals:**
+- Custom domains per instance (use Cloudflare zone's wildcard)
+- Advanced tunnel features (load balancing, failover, ingress rules)
+- Replacing Traefik for the main app (API + frontend)
+- Supporting non-HTTP protocols (TCP/UDP raw tunneling)
+
+## Decisions
+
+### Cloudflare API vs cloudflared CLI
+
+**Decision:** Use the Cloudflare REST API to create/manage tunnels, not the `cloudflared` CLI.
+
+**Rationale:**
+- The API gives us programmatic control without parsing CLI output
+- We can use `httpx` (already a dependency) instead of subprocess calls
+- Easier to test and mock
+
+**Alternative considered:** Running `cloudflared tunnel create` via subprocess
+- Rejected: Fragile, harder to test, requires cloudflared binary in API container
+
+### Architecture: cloudflared as a separate container
+
+**Decision:** Run `cloudflared` as a standalone Docker service that connects to Cloudflare and routes traffic.
+
+**Rationale:**
+- Separation of concerns: API manages tunnels, cloudflared handles connectivity
+- The cloudflared container can access the Docker internal network where instances run
+- Easier to scale/restart independently
+

+│  (tool instances on Docker network with DNS names)          │
+└─────────────────────────────────────────────────────────────┘
+```
+
+### Subdomain naming
+
+**Decision:** Use `instance-{short-uuid}.{zone}` format (e.g., `instance-a1b2c3d4.headquarter.commumedia.org`)
+
+**Rationale:**
+- Predictable and URL-safe
+- Short enough to be readable
+- UUID ensures uniqueness without exposing internal IDs
+
+### Tunnel lifecycle
+
+**Decision:** Create tunnel on instance start, delete on instance stop/delete.
+
+**Flow:**
+1. User clicks "Start"
+2. Backend creates Cloudflare tunnel via API
+3. Backend creates DNS CNAME record: `instance-abc123` → `{tunnel-id}.cfargotunnel.com`
+4. Backend stores `tunnel_id` and `public_url` in ToolInstance
+5. cloudflared container routes traffic to container:port
+6. On stop: delete DNS record, delete tunnel
+
+### cloudflared configuration
+
+**Decision:** Use a single cloudflared container with dynamic config file updates.
+
+**Approach:**
+- The cloudflared container reads an `config.yml` file mounted as a volume
+- The API writes ingress rules to this file when instances start/stop
+- cloudflared automatically reloads the config (or we restart the container)
+
+```yaml
+# /etc/cloudflared/config.yml
+tunnel: {tunnel-token}
+credentials-file: /etc/cloudflared/credentials.json
+ingress:
+  - hostname: instance-abc123.headquarter.commumedia.org
+    service: http://code-server-repo-abc123:8443
+  - hostname: instance-xyz789.headquarter.commumedia.org
+    service: http://jupyter-repo-def:8888
+  - service: http_status:404
+```
+
+### Authentication
+
+**Decision:** Cloudflare tunnels provide HTTPS but do NOT handle app-level auth. Tool instances without built-in auth (like code-server) will be publicly accessible.
+
+**Rationale:**
+- Cloudflare Access could add auth, but adds complexity
+- Many tools (code-server) have their own password/auth mechanisms
+- Users should configure tool-level auth via ToolConfig
+
+**Mitigation:** Document that users must configure tool passwords via ToolConfig (e.g., `PASSWORD` env for code-server).
+
+## Risks / Trade-offs
+
+**[Risk]** Cloudflare API rate limits (1200 requests/5 min)
+→ **Mitigation:** Tunnel creation is infrequent (user-initiated), unlikely to hit limits
+
+**[Risk]** cloudflared container becomes a single point of failure
+→ **Mitigation:** It's stateless; can be restarted quickly. All instances share one cloudflared.
+
+**[Risk]** Subdomain enumeration exposes running instances
+→ **Mitigation:** UUID-based names are hard to guess. Consider adding Cloudflare Access in future.
+
+**[Risk]** cloudflared config file updates require container restart
+→ **Mitigation:** Investigate `cloudflared --no-autoupdate` with config watch, or accept brief restart
+
+**[Risk]** Tool instances publicly accessible without auth
+→ **Mitigation:** Document security best practices, recommend setting tool passwords
+
+## Migration Plan
+
+1. Deploy cloudflared container with base config
+2. Add Cloudflare env vars to API container
+3. Deploy backend changes (tunnel service, updated lifecycle)
+4. Deploy frontend changes (use public_url instead of proxy)
+5. Test with code-server instance
+6. Remove old proxy endpoint code
+
+## Open Questions
+
+- Should we add Cloudflare Access (Zero Trust) to protect instances?
+- Do we need to support custom subdomains (e.g., `myproject.headquarter.commumedia.org`)?
+- Should we keep the proxy endpoint as a fallback?

+## Why
+
+The current approach of proxying tool instances through the backend API is fragile and creates a bottleneck. Every HTTP request and WebSocket connection to a tool instance (code-server, jupyter, etc.) must pass through the FastAPI application, adding latency and consuming API resources. Cloudflare Tunnel provides a robust alternative: each instance gets its own public subdomain with automatic HTTPS, without exposing ports or requiring complex reverse proxy rules.
+
+## What Changes
+
+- Replace the API proxy endpoint (`/instances/{id}/proxy/`) with Cloudflare Tunnel integration
+- Run a `cloudflared` container alongside the API that manages tunnels programmatically via the Cloudflare API
+- When a tool instance starts, create a unique Cloudflare Tunnel and DNS record pointing to the instance's internal container name and port
+- Store the public URL (e.g., `https://instance-abc123.headquarter.commumedia.org`) in the ToolInstance model
+- Update the frontend "Open" button to use the Cloudflare URL instead of the proxy path
+- Remove the proxy endpoint and related code (instance_proxy.py)
+- **BREAKING**: The `/instances/{id}/proxy/{path:path}` endpoint will be removed
+
+## Capabilities
+
+### New Capabilities
+
+- `cloudflare-tunnel-management`: Creating, deleting, and managing Cloudflare tunnels for tool instances via the Cloudflare API
+
+### Modified Capabilities
+
+- `instance-proxy`: The current proxy-based approach will be replaced by Cloudflare tunnels. The requirement that "The API SHALL expose an endpoint that forwards HTTP requests" is replaced by "The system SHALL provide a public URL for each running instance."
+
+## Impact
+
+- Backend: New Cloudflare tunnel service, updated instance lifecycle (create tunnel on start, delete on stop), removed proxy code
+- Frontend: Update "Open" links to use public Cloudflare URLs
+- Infrastructure: New `cloudflared` Docker service, Cloudflare API token required
+- Environment: New env vars: `CLOUDFLARE_API_TOKEN`, `CLOUDFLARE_ACCOUNT_ID`, `CLOUDFLARE_ZONE_ID`
+- Docker: Cloudflared container must be on the same network as tool instances

+## ADDED Requirements
+
+### Requirement: System creates Cloudflare tunnel on instance start
+When a tool instance is started, the system SHALL create a Cloudflare tunnel and DNS record to expose it publicly.
+
+#### Scenario: Start instance creates tunnel
+- **WHEN** a user starts a tool instance
+- **THEN** the system calls the Cloudflare API to create a tunnel
+- **AND** creates a CNAME DNS record for `instance-{id}.{zone}`
+- **AND** stores the tunnel ID and public URL in the database
+
+#### Scenario: Tunnel points to correct container
+- **WHEN** a tunnel is created for an instance

+
+### Requirement: System deletes Cloudflare tunnel on instance stop
+When a tool instance is stopped or deleted, the system SHALL clean up the associated Cloudflare tunnel and DNS record.
+
+#### Scenario: Stop instance deletes tunnel
+- **WHEN** a user stops a running instance
+- **THEN** the system deletes the DNS record
+- **AND** deletes the Cloudflare tunnel
+
+#### Scenario: Delete instance cleans up tunnel
+- **WHEN** a user deletes an instance
+- **AND** the instance has an active tunnel
+- **THEN** the system deletes both the DNS record and the tunnel
+
+### Requirement: Frontend uses public URL for instance access
+The frontend SHALL display and link to the public Cloudflare URL for running instances.
+
+#### Scenario: Open button uses public URL
+- **WHEN** a user views a running instance
+- **THEN** the "Open" button links to the instance's public URL
+- **AND** the URL opens in a new tab
+
+#### Scenario: Session list shows public URL
+- **WHEN** a user views their sessions
+- **THEN** each running session displays its public URL
+
+### Requirement: Only instance owner can start/stop/delete tunnels
+The system SHALL verify that only the instance owner can trigger tunnel creation or deletion.
+
+#### Scenario: Owner starts instance
+- **WHEN** the instance owner clicks "Start"
+- **THEN** the tunnel is created successfully
+
+#### Scenario: Non-owner attempts to start
+- **WHEN** a non-owner attempts to start an instance
+- **THEN** the request returns 403 Forbidden

+## Context
+
+The current repository creation flow already supports cloning remote repositories via `remote_url` and can normalize pasted browser URLs. However, the UI asks for a full URL, which is awkward for the fixed provider `git.commumedia.org`. The requested behavior is to enter `owner` and `repo`, check whether the repository exists, and clone only if it does.
+
+## Goals / Non-Goals
+
+**Goals:**
+- Accept SSH-only `owner` and `repo` inputs for cloning from `git.commumedia.org`
+- Verify repository existence before clone
+- Preserve full URL paste as a fallback path
+- Preserve blank repository creation
+- Reuse the existing repository create endpoint and shared dialog
+
+**Non-Goals:**
+- Supporting multiple git providers
+- Adding a remote repository discovery API
+- Supporting HTTPS clone flow for the new structured path
+- Changing repository storage or clone behavior beyond preflight validation
+
+## Decisions
+
+**1. Provider assumption**
+- Hardcode `git.commumedia.org` for the structured clone path
+- Build SSH URLs as `git@git.commumedia.org:{owner}/{repo}.git`
+
+**2. Existence check**
+- Use `git ls-remote` on the constructed SSH URL before cloning
+- If the command fails, surface a repository-not-found/inaccessible error and do not clone
+
+**3. UI structure**
+- Keep the shared repository creation dialog as the single entry point
+- In clone mode, collect `owner` and `repo` instead of asking for a full URL
+- Keep an advanced paste-URL fallback for existing behavior and browser URL parsing
+- Keep blank repository creation available in the same dialog
+
+**4. Backend behavior**
+- Reuse `POST /projects/{project_id}/repositories`
+- Add preflight logic before the existing `git clone --mirror`
+- Leave the database schema unchanged
+
+## Risks / Trade-offs
+
+**[Risk] SSH auth may still fail even if the repo exists** → Mitigation: preflight error should be explicit and user-facing.
+**[Risk] Command availability** → Mitigation: reuse the same `git` dependency already required for cloning.
+**[Risk] UI complexity** → Mitigation: keep the dialog shared and minimal, with fallback URL paste.

+## Why
+
+Repository creation already supports cloning from a remote URL, but the current UI only accepts a full URL. For the common fixed-provider case (`git.commumedia.org`), users should be able to enter `owner` and `repo` and have the app verify the repository exists before cloning. If the repository does not exist, the app should surface a clear error. Existing blank repository creation must remain available.
+
+## What Changes
+
+- Change the shared repository create dialog to support an SSH-only clone form with `owner` and `repo`
+- Build the clone target as `git@git.commumedia.org:{owner}/{repo}.git`
+- Preflight clone targets with `git ls-remote` before cloning
+- Return a clear error when the repository is missing or inaccessible
+- Keep the current full URL paste flow as an advanced fallback
+- Keep blank repository creation as a fallback option
