Merge branch 'dev' of ssh://git.commumedia.org:2222/alex/headquarter into dev

- Add clone_mode and branch fields to tool_instances
- Add ssh_key_id to git_repositories for per-repo SSH key assignment
- Implement host-side git cloning with branch selection (default: main)
- Mount SSH keys into containers for git operations in clone mode
- Add dirty state check on clone-mode instance deletion with confirmation
- Update SessionsPage with mount/clone selector, branch input, SSH key display
- Add SSH key selector to repository creation form
- Add dirty delete confirmation modal with changed files list
- Update API schemas and endpoints for new fields
- Sync delta specs to main specs (git-repo, tool-instances, repo-clone-mode)
- Archive completed OpenSpec change: repo-clone-mode-with-ssh
- Document git requirement for custom tool types

Quality gates: Frontend typecheck and build passed
OpenSpec: repo-clone-mode-with-ssh archived with all tasks complete

+## Context
+
+Currently, tool types use a JSON `interfaces` array (e.g., `["web"]`, `["terminal"]`, `["web", "terminal"]`) to define what interfaces a tool supports. This was designed for flexibility but in practice:
+1. No tool needs both web and terminal simultaneously
+2. Terminal tools don't expose ports or need tunneling
+3. The UI shows checkboxes for both, allowing invalid multi-select combinations
+
+The database migration `0008_tool_type_category` added the `interfaces` JSON column. All existing records use `["web"]` or `["terminal"]` as the first (and only) element.
+
+## Goals / Non-Goals
+
+**Goals:**
+- Replace `interfaces` array with single `interface_type` string column
+- Add `requires_port` boolean to indicate if port/tunnel config is relevant
+- Update UI to use dropdown instead of checkboxes
+- Conditionally hide port fields for terminal tools
+- Migrate existing data safely
+
+**Non-Goals:**
+- No changes to tool instance runtime behavior
+- No changes to tunnel/port infrastructure
+- No changes to existing tool configs (port_override remains in schema)
+
+## Decisions
+
+**Decision: Replace interfaces array with single interface_type string**
+- Rationale: Simplifies model, API, and UI. No legitimate use case for multiple interfaces.
+- Alternative: Keep array but enforce single item — rejected because it keeps unnecessary complexity
+
+**Decision: Add requires_port boolean instead of inferring from interface_type**
+- Rationale: Explicit is better than implicit. Future interface types may have different port needs.
+- Alternative: Infer from interface_type === "web" — rejected for flexibility
+
+**Decision: Default requires_port = true for existing records, then update per actual type**
+- Rationale: Most existing tools are web-based. Safer default.
+- Migration will inspect existing interfaces[0] to set correct value.
+
+**Decision: Keep port_override in tool_configs schema**
+- Rationale: Even terminal tools might need port overrides in edge cases. The UI just hides it.
+- Alternative: Remove column — rejected to avoid destructive migration
+
+## Risks / Trade-offs
+
+- **[Risk]** Existing API consumers expect `interfaces` array
+  - **Mitigation:** This is a **BREAKING** change. Update frontend simultaneously. Document in changelog.
+- **[Risk]** Data migration fails for unexpected interfaces values
+  - **Mitigation:** Migration takes first array element. Add fallback to "web" with requires_port=true.
+- **[Risk]** Tests break across backend and frontend
+  - **Mitigation:** Update all test fixtures and assertions in single commit.
+
+## Migration Plan
+
+1. Create Alembic migration to:
+   - Add `interface_type` string column (nullable temporarily)
+   - Add `requires_port` boolean column (default true)
+   - Migrate data: `interface_type = interfaces[0]`, `requires_port = (interfaces[0] == "web")`
+   - Drop `interfaces` column
+   - Make `interface_type` non-nullable
+2. Update Pydantic schemas (Create/Update/Response)
+3. Update SQLAlchemy model
+4. Update frontend types and API client
+5. Update tool workshop form (dropdown + conditional fields)
+6. Update built-in seed data
+7. Update tests
+8. Run full test suite

+## Why
+
+Currently, tool types support multiple interfaces (e.g., `web` and `terminal` simultaneously), but in practice each tool serves a single purpose and should have one clear interface type. Additionally, terminal tools don't need ports or tunneling capabilities, yet the UI always shows port configuration. This creates confusion and allows invalid configurations.
+
+## What Changes
+
+- **BREAKING**: Change `interfaces` from an array (`["web"]`) to a single string (`"web"` or `"terminal"`) in the ToolType model, API, and frontend
+- Add `requires_port` boolean field to ToolType model — `true` for web tools, `false` for terminal tools
+- Update frontend UI to use a dropdown for interface type selection (single choice)
+- Conditionally show/hide port-related fields based on `requires_port`
+- Add database migration to convert existing `interfaces` arrays to single values and set `requires_port`
+- Update built-in tool types (code-server, jupyter-notebook) to use new schema
+- Update tool workshop page to reflect the single-type dropdown and conditional port visibility
+
+## Capabilities
+
+### New Capabilities
+- `tool-type-single-interface`: Enforce single interface type per tool with dropdown selection
+- `tool-type-port-visibility`: Conditionally show port/tunnel config based on tool interface type
+
+### Modified Capabilities
+- `tool-types-definition`: Update model and API to replace `interfaces` array with single `interface_type` string and add `requires_port`
+- `frontend-foundation`: Update tool workshop UI for single interface dropdown and conditional port fields
+
+## Impact
+
+- Database: Migration to change `interfaces` JSON column to `interface_type` string + add `requires_port` boolean
+- Backend API: Update Pydantic schemas, SQLAlchemy model, validation logic
+- Frontend: Update TypeScript types, tool workshop form, API client
+- Existing tool configs: No direct impact, but port_override field becomes irrelevant for terminal tools
+- Tests: Update test data and assertions for new schema

+  - `requires_port`: boolean indicating if port/tunnel configuration is needed
+  - `compose_template`: Docker Compose YAML string
+  - `dockerfile_template`: Dockerfile string
+  - `definition_type`: string — "compose" or "dockerfile"
+  - `required_variables`: list of required template variables
+  - `is_builtin`: boolean flag for system-defined types
+  - `created_at`/`updated_at`: timestamps
+
+### Requirement: CRUD API Endpoints
+The system SHALL provide REST API endpoints for tool type management.
+
+#### Scenario: Create tool type
+- GIVEN an admin user
+- WHEN they POST /api/tool-types with valid data

+- AND validates `interface_type` is "web" or "terminal" if provided
+- AND re-validates the compose template
+- AND returns 200 OK with updated tool type
+
+## REMOVED Requirements
+
+### Requirement: Multiple interfaces support
+**Reason**: Tool types now use a single `interface_type` instead of an array of interfaces. No tool legitimately needs both web and terminal interfaces simultaneously.
+**Migration**: Use `interface_type` field (string) instead of `interfaces` array. Set to "web" or "terminal".

+- AND port-related configuration is shown in the UI
+
+#### Scenario: Terminal tool does not require port
+- GIVEN a tool type with `interface_type` = "terminal"
+- WHEN the tool type is created or updated
+- THEN `requires_port` SHALL default to false
+- AND port-related configuration is hidden in the UI
+
+### Requirement: Single interface validation
+The system SHALL enforce that each tool type has exactly one interface type.

+## Context
+
+Currently, all tool instances bind-mount the host repository path via `{{REPO_PATH}}` substitution in compose templates. The repository model (`GitRepository`) has no SSH key association. The instance model (`ToolInstance`) has no concept of repository access mode.
+
+Users want two modes:
+1. **Mount** (current): Live sync with working copy on host
+2. **Clone** (new): Fresh isolated copy with full git history inside the container
+
+The SSH key system already exists with encrypted private keys in the database. Keys can be project-scoped or user-scoped.
+
+## Goals / Non-Goals
+
+**Goals:**
+- Allow per-instance choice between mount and clone mode
+- Support branch selection for clone mode (default: main)
+- Enable git operations inside containers via SSH key mounting
+- Protect against accidental data loss with dirty check on clone deletion
+- Allow SSH key assignment at repository creation and later modification
+
+**Non-Goals:**
+- Modifying existing tool type compose templates
+- Installing git in containers (assumes tool images have git or install it)
+- Multiple SSH keys per container
+- Automatic push/pull/sync between host and container
+- Shallow clones (full history only)
+
+## Decisions
+
+### 1. Host-Side Clone (not in-container)
+
+**Decision**: Clone happens on the host before container start, not inside the container.
+
+**Rationale**:
+- No changes to compose templates required
+- Works with all existing tool types immediately
+- No need for git/SSH inside every container image
+- Host has direct filesystem access to the clone
+- Easier error handling and rollback
+
+**Alternative considered**: In-container clone via command override. Rejected because it requires git in every image, SSH auth setup inside containers, and makes error handling fragile.
+
+### 2. SSH Key Mounting via `_modify_compose_file`
+
+**Decision**: Inject SSH key volume dynamically at container start time using the existing `_modify_compose_file` helper.
+
+**Rationale**:
+- Zero changes to tool type definitions
+- Consistent with how other runtime overrides work (port, command, working_dir, extra_volumes)
+- Mounts the `.ssh/` directory with key + config into container
+
+**Implementation**:
+```
+instance_dir/.ssh/
+  id_ed25519      (decrypted private key, mode 600)
+  id_ed25519.pub  (public key)
+  config          (StrictHostKeyChecking no)
+```
+
+Mounted as: `instance_dir/.ssh:/root/.ssh:ro` (or appropriate home dir)
+
+### 3. Single SSH Key per Repository
+
+**Decision**: The SSH key is stored on `GitRepository` and used for both clone and container access.
+
+**Rationale**:
+- Natural association: a repository's clone URL determines which SSH key is needed
+- Simpler UX: one key per repo, not per session
+- Session creation can override (future enhancement) but defaults to repo key
+
+### 4. Dirty Check via `git status --short`
+
+**Decision**: Check for uncommitted changes using `git status --short` before allowing deletion of clone-mode instances.
+
+**Rationale**:
+- Simple and reliable
+- Catches staged, unstaged, and untracked files
+- Fast (local filesystem operation)
+
+## Risks / Trade-offs
+
+**[Risk] Disk space usage** → Each clone-mode instance duplicates the full repository. Mitigation: Instance deletion removes the clone directory.
+
+**[Risk] Clone time for large repos** → Synchronous clone during instance creation may timeout. Mitigation: No timeout on clone operation; consider async clone in future.
+
+**[Risk] SSH key permissions in containers** → Some containers run as non-root users. The `.ssh` directory mount needs correct ownership. Mitigation: Mount as read-only; container's entrypoint may need to copy to writable location if needed.
+
+**[Risk] Git not installed in custom tool images** → User-defined tool types may not have git. Mitigation: Document requirement; built-in types already have or install git.
+
+**[Risk] SSH host key checking** → Cloning from new hosts may fail. Mitigation: SSH config sets `StrictHostKeyChecking no` for clone operations.
+
+## Migration Plan
+
+1. Run Alembic migrations to add new columns
+2. Existing instances default to `clone_mode='mount'` (no behavior change)
+3. Existing repositories have `ssh_key_id=null` (no behavior change until assigned)
+4. No data migration needed
+
+## Open Questions
+
+- Should the `.ssh` mount be read-only or writable? (Writable needed if container generates new keys, but we don't support that)
+- Should we support submodules in cloned repos?

+## Why
+
+Currently all tool instances bind-mount the host repository directory, giving containers live access to the working copy. Users need the ability to launch instances with an isolated fresh clone instead — useful for experimentation, clean-room development, or running tools that modify files without affecting the host copy. Additionally, containers need SSH key access to perform git operations (push/pull) inside the clone.
+
+## What Changes
+
+- **Repository-level SSH key assignment**: Each `GitRepository` can be associated with an SSH key (used for cloning and container git access). Configurable at creation time and editable later.
+- **Clone mode for tool instances**: When creating a tool instance, users can choose between:
+  - **Mount** (default): Bind-mount the host repository directory (current behavior)
+  - **Clone**: Clone the repository into the instance directory with full history
+- **Branch selection**: When clone mode is selected, users can specify a branch (defaults to `main`).
+- **SSH key mounting**: The repository's SSH key is decrypted and mounted into the container's `~/.ssh/` directory, enabling git operations inside the container.
+- **Dirty check on delete**: When deleting a clone-mode instance, check for uncommitted changes in the cloned repository. If changes exist, warn the user and require confirmation before deletion.
+- **Frontend UI updates**: Sessions page gets a repository access mode selector (mount/clone), branch input, and SSH key selector when clone is chosen.
+- **Backend API updates**: `POST /instances` accepts `clone_mode` and `branch`; new endpoint for updating repository SSH key.
+- **Database migrations**: Add `ssh_key_id` to `git_repositories`, `clone_mode` and `branch` to `tool_instances`.
+
+## Capabilities
+
+### New Capabilities
+- `repo-clone-mode`: Repository clone mode with host-side cloning, branch selection, and SSH key mounting for container git access.
+
+### Modified Capabilities
+- `git-repo`: Add `ssh_key_id` field and API for associating SSH keys with repositories.
+- `tool-instances`: Extend instance creation to support `clone_mode` and `branch`, mount SSH keys at startup, and perform dirty check on deletion.
+
+## Impact
+
+- **Database**: Migrations for `git_repositories.ssh_key_id`, `tool_instances.clone_mode`, `tool_instances.branch`
+- **Backend API**: `POST /instances` schema change, new `PATCH /repositories/{id}/ssh-key` endpoint, instance delete logic update
+- **Frontend**: SessionsPage form additions, confirmation modal for dirty delete
+- **Docker**: Dynamic SSH key volume injection via `_modify_compose_file`
+- **Tool types**: Built-in tool images assumed to have git installed (code-server, jupyter do; opencode template already installs git)
