refactor: extract Pydantic schemas into schemas/ subpackages

Extract inline Pydantic models from 9 API routers into dedicated
schema modules under schemas/:

- schemas/tool/tool_type.py — ToolTypeCreate, ToolTypeUpdate, etc.
- schemas/tool/tool_instance.py — CreateInstanceRequest, StartInstanceRequest
- schemas/config/config_profile.py — ConfigProfileCreate, ConfigProfileUpdate,
  ConfigProfileResponse, DefaultProfilesUpdate, ValidateGitUrlRequest, etc.
- schemas/system/health.py — DatabaseHealth, DiskHealth, HealthResponse, etc.
- schemas/user/user.py — UserProfileResponse, UserProfileUpdate
- schemas/user/user_config.py — UserConfigResponse, UserConfigUpdate
- schemas/project/project.py — ProjectCreate, ProjectUpdate, etc.
- schemas/project/ssh_key.py — SSHKeyCreate, SSHKeyResponse, etc.
- schemas/project/git_repository.py — GitRepositoryCreate, etc.

API routers now import from src.schemas.* instead of defining inline.
Net change: -548 lines across 16 files.

Quality gates: py_compile passed, ruff passed on all 18 files.

+## Context
+
+Current `dev` has all behavioral features from the overwritten `main` merge, but the code structure is pre-refactor:
+- Monolithic `api/tool_instances.py` (~3000 lines)
+- Monolithic `api/config_profiles.py` (~1000 lines)
+- Monolithic `services/docker.py`
+- No `schemas/` directory
+- Flat frontend component structure with inconsistent naming
+
+The `b6f89f9` merge from `main` had a clean refactoring that we need to redo, but adapted to our current reality.
+
+## Goals / Non-Goals
+
+**Goals:**
+- Extract Pydantic schemas from API routers into `src/schemas/`
+- Split `services/docker.py` into `services/docker/` package
+- Extract instance lifecycle logic from `api/tool_instances.py` into `services/instance_lifecycle.py`
+- Extract config profile business logic from `api/config_profiles.py` into `services/config_profiles.py`
+- Add `get_current_user` auth dependency and migrate routers that need the full user object
+- Reorganize frontend components into `features/` directories
+- Standardize frontend API file naming to kebab-case
+- Standardize frontend page naming to `*Page.tsx`
+
+**Non-Goals:**
+- Changing any API request/response shapes
+- Changing any database schemas
+- Adding new features
+- Modifying frontend component behavior or styling
+- Converting `ConfigProfile` mounts from JSON to relation tables (out of scope — would require migration)
+
+## Decisions
+
+### 0. Submodule Rule: Max 5–10 Files Per Directory
+**Decision:** Every directory that functions as a Python module must contain at most 5–10 `.py` files. When a module grows beyond this, split it into a package with submodules.
+**Rationale:** Prevents monolithic directories, makes navigation predictable, and keeps cognitive load bounded.
+
+### 1. Schema Extraction: Domain Subpackages
+**Decision:** Extract Pydantic models into `schemas/` subpackages by domain:
+- `schemas/tool/` — tool_type.py, tool_instance.py
+- `schemas/config/` — config_profile.py
+- `schemas/user/` — user.py, user_config.py
+- `schemas/project/` — project.py, git_repository.py, ssh_key.py
+- `schemas/system/` — health.py
+**Rationale:** Keeps schemas close to their domain. Each subpackage has ≤5 files.
+
+### 2. API Router Subpackages
+**Decision:** Split `api/` into domain subpackages:
+- `api/tool/` — tool_instances.py, tool_types.py, tool_definitions.py, tool_types_validation.py, sessions.py
+- `api/config/` — config_profiles.py, user_config.py
+- `api/workspace/` — workspaces.py, workspace_files.py, workspace_git.py, workspace_instances.py
+- `api/user/` — users.py, auth.py, ssh_keys.py
+- `api/project/` — projects.py, git_repositories.py
+- `api/system/` — health.py, events.py, notifications.py, dashboard.py, terminal.py, instance_proxy.py
+**Rationale:** `api/` currently has ~22 files. Splitting into 6 subpackages keeps each at 2–6 files.
+
+### 3. Service Subpackages
+**Decision:** Split `services/` into subpackages:
+- `services/docker/` — compose.py, container.py, config_staging.py, tunnel.py, __init__.py
+- `services/instance/` — instance_lifecycle.py, lifecycle_hooks.py, health_monitor.py, event_bus.py
+- `services/config/` — config_profile_resolver.py, config_profiles.py
+- `services/git/` — clone.py, git_operations.py, git_service.py
+- `services/build/` — docker_build.py, manifest_compiler.py
+- `services/terminal/` — terminal_manager.py, terminal_session.py
+- `services/shared/` — tunnel.py, notification_service.py, file_service.py, permission_fixer.py, readiness_probe.py, ssh_keys.py, workspace_manager.py, correlation.py
+**Rationale:** `services/` currently has ~20 files. Subpackages keep each at ≤8 files.
+
+### 4. Model Subpackages
+**Decision:** Split `models/` into subpackages:
+- `models/tool/` — tool_type.py, tool_instance.py, tool_definition_manifest.py
+- `models/config/` — config_profile.py, config_include.py, config_mount.py
+- `models/user/` — user.py, user_config.py, ssh_key.py
+- `models/project/` — project.py, git_repository.py, workspace.py
+- `models/system/` — health_check.py, notification.py, instance_event.py, terminal_session.py
+- `models/base.py` stays at root
+**Rationale:** `models/` currently has ~15 files. Subpackages keep each at ≤4 files.
+
+### 5. Docker Service Split: Functional Boundaries
+**Decision:** Split by responsibility:
+- `compose.py` — compose file generation, modification, port injection, network injection
+- `container.py` — container status, IP lookup, network connect, logs
+- `config_staging.py` — staging config files into instance directories
+- `tunnel.py` — extracting tunnel URLs from cloudflared output
+**Rationale:** Each module has a single reason to change. `docker.py` mixed compose logic with container runtime queries.
+
+### 6. Instance Lifecycle: Service Receives Raw Params, Not Request Objects
+**Decision:** Service functions receive model instances and primitive parameters, not FastAPI request objects.
+**Example:** `create_instance(session, user, project, repo, tool_type, data: CreateInstanceRequest)` → service extracts fields.
+**Rationale:** Keeps service layer independent of HTTP framework. Easier to test.
+
+### 7. Auth Pattern: Gradual Migration, Not Big Bang
+**Decision:** Add `get_current_user` alongside existing `get_current_user_id`. Migrate routers incrementally.
+**Rationale:** Reduces risk. Endpoints that only need the ID can keep the old pattern.
+
+### 8. Frontend Naming: Align with `b6f89f9` Conventions
+**Decision:** Use kebab-case for API files, PascalCase for page files with `Page` suffix, `features/` for component directories.
+**Rationale:** Matches the `b6f89f9` structure that was already reviewed and accepted.

+## Risks / Trade-offs
+
+**[Risk] Import cycles during extraction** → **Mitigation:** Extract schemas first (no service dependencies), then services, then thin routers last. Use TYPE_CHECKING guards.
+
+**[Risk] Merge conflicts with in-flight features** → **Mitigation:** Coordinate timing. This refactor should be the only large change on `dev` while it's in progress. Freeze other backend work.
+
+**[Risk] Frontend renaming breaks imports** → **Mitigation:** Use `git mv` for renames so git tracks history. Update all imports in a single commit.
+
+**[Risk] Missing re-export in docker/__init__.py breaks consumers** → **Mitigation:** After splitting, run a full import test across all backend files. Add any missing re-exports.
+
+## Migration Plan
+
+1. **Phase 1: Schemas** — Extract all Pydantic models into `schemas/`. Update imports in API routers. No logic changes.
+2. **Phase 2: Services** — Split `docker.py`, extract `instance_lifecycle.py`, extract `config_profiles.py`. Update imports.
+3. **Phase 3: Auth** — Add `get_current_user`, migrate routers that need the full user object.
+4. **Phase 4: Frontend** — Rename files, move components, update imports.
+5. **Phase 5: Verification** — Run full test suite, typecheck, build.

+## Why
+
+The `main` branch was previously merged into `dev` (commit `b6f89f9`) bringing a large structural refactoring: schema extraction, service splitting, auth dependency pattern changes, and frontend reorganization. This merge was later overwritten when `dev` was reset to a pre-merge clean state (`51a399c`).
+
+We have since forward-ported all behavioral features (built-in tool type seeding, config profile defaults, unique constraints, SSH key mounting, terminal backend, etc.) onto the clean `dev` base. **The codebase now works functionally but lacks the structural cleanliness of the refactoring.**
+
+Monolithic files make the backend harder to navigate, test, and maintain:
+- `api/tool_instances.py` is ~3000 lines (mixing HTTP handling with Docker orchestration)
+- `api/config_profiles.py` is ~1000 lines (mixing HTTP handling with business logic)
+- `services/docker.py` is a monolith of ~600 lines covering compose, container, and tunnel logic
+- Frontend API files use inconsistent naming (`tool_types.ts` vs `tool-types.ts`)
+- Frontend components are flat in `components/` instead of organized by feature domain
+
+## What Changes
+
+Redo the structural refactoring from `b6f89f9`, **adapted to current dev reality**:
+
+1. **Backend schema extraction** — Extract Pydantic request/response schemas from API routers into `apps/api/src/schemas/`
+2. **Backend service splits** — Split `services/docker.py` into `services/docker/` package; extract `services/instance_lifecycle.py` and `services/config_profiles.py`
+3. **Auth dependency refactor** — Change from `get_current_user_id` + manual `_get_user` calls to `get_current_user` dependency returning `User` directly
+4. **Frontend reorganization** — Move components into `features/` directories; rename API files to kebab-case
+
+**No behavioral changes.** This is a pure structural refactor. All existing endpoints, models, and UI flows remain identical.
+
+## Capabilities
+
+### New Capabilities
+- None (pure refactor)
+
+### Modified Capabilities
+- `backend-structure`: Cleaner module boundaries, smaller files, separated concerns
+- `frontend-structure`: Feature-organized components, consistent file naming
+
+## Impact
+
+- **Backend**: `apps/api/src/schemas/*` (new), `apps/api/src/services/docker/*` (new package), `apps/api/src/services/instance_lifecycle.py` (new), `apps/api/src/services/config_profiles.py` (new)
+- **Backend**: `apps/api/src/api/*.py` (reduced in size, imports change)
+- **Backend**: `apps/api/src/auth/dependencies.py` (new `get_current_user`)
+- **Frontend**: `apps/web/src/components/features/*` (new directories), `apps/web/src/api/*` (renamed to kebab-case)
+- **Frontend**: `apps/web/src/pages/*` (renamed to `*Page.tsx`)
+
+## Exclusions (Already Done)
+
+The following behavioral features from `b6f89f9` are **already present** in current `dev` and out of scope for this refactor:
+- Built-in tool type seeding (`src/seeds/builtin_tool_types.py`)
+- Config profile default management (endpoints + `UserConfig` properties)
+- Config profile unique constraint (`uq_config_profiles_user_name`)
+- SSH key mounting in instance lifecycle
+- Terminal backend (WebSocket, session management)
+- Tunnel URL regex fix
+- Session auto-numbering
+- Config profile resolver (`services/config_profile_resolver.py`)

+## Scope
+
+This change is a **pure structural refactoring** of the backend and frontend codebase. No API contracts, database schemas, or user-facing behaviors change.
+
+### In Scope
+
+1. **Schema extraction** (`apps/api/src/schemas/`)
+   - Extract Pydantic models from API routers into dedicated schema modules
+   - Schemas to extract: `tool_type`, `tool_instance`, `config_profile`, `user`, `user_config`, `project`, `ssh_key`, `git_repository`, `health`
+   - Each API router imports schemas from `src.schemas.*` instead of defining inline
+
+2. **Docker service package** (`apps/api/src/services/docker/`)
+   - Split `services/docker.py` monolith into focused modules:
+     - `docker/compose.py` — compose file generation, modification, validation
+     - `docker/container.py` — container lifecycle (status, IP, network, logs)
+     - `docker/config_staging.py` — config file staging for instances
+     - `docker/tunnel.py` — tunnel URL extraction (moved from `services/tunnel.py`)
+     - `docker/__init__.py` — re-exports for backward compatibility
+   - Update all imports across the backend
+
+3. **Instance lifecycle extraction** (`apps/api/src/services/instance_lifecycle.py`)
+   - Extract instance creation, start, stop, restart, and deletion logic from `api/tool_instances.py`
+   - The API router becomes thin: validates auth, calls service, returns response
+   - Service functions are async and receive `AsyncSession`, models, and raw parameters
+
+4. **Config profile service extraction** (`apps/api/src/services/config_profiles.py`)
+   - Extract business logic from `api/config_profiles.py`: CRUD helpers, validation, default profile management
+   - API router delegates to service functions
+
+5. **Auth dependency refactor** (`apps/api/src/auth/dependencies.py`)
+   - Add `get_current_user` dependency that returns a `User` model directly
+   - Update API routers to use `user: User = Depends(get_current_user)` where the full user object is needed
+   - Keep `get_current_user_id` for endpoints that only need the ID
+
+6. **Frontend reorganization**
+   - Move components into `features/` directories by domain:
+     - `features/git/` — CommitDialog, FileBrowser, FileEditor, GitToolbar, MergeDialog, WorkspaceSidebar
+     - `features/dashboard/` — ActiveSessionsList, DashboardSummary, ProjectsSection, QuickCreateForm, RecentSessionsSection
+     - `features/project/` — RepositoriesSettingsTab
+     - `features/tool-workshop/` — ToolTypesTab (already exists)
+   - Rename API files from snake_case to kebab-case:
+     - `tool_types.ts` → `tool-types.ts`
+     - `ssh_keys.ts` → `ssh-keys.ts`
+     - `git_repositories.ts` → `git-repositories.ts`
+   - Rename page files to `*Page.tsx`:
+     - `dashboard.tsx` → `DashboardPage.tsx`
+     - `projects.tsx` → `ProjectsPage.tsx`
+     - etc.
+
+### Out of Scope
+
+- Any new features or behavioral changes
+- Database schema changes (no migrations)
+- API contract changes (same endpoints, same request/response shapes)
+- Frontend UI behavior changes (same components, same interactions)
+- Removing or modifying the `ConfigProfileInclude` model (already exists as a relation)
+- Extracting `ConfigMount` into a separate model (current dev uses JSON arrays; this is a schema decision, not a refactor)
+- Changes to `tool_definition_manifest` or `workspace` models
+
+## Acceptance Criteria
+
+1. All existing tests pass without modification (behavior unchanged)
+2. All existing API endpoints return identical responses for identical requests
+3. All frontend pages render identically
+4. `docker compose up` starts successfully
+5. Backend `ruff check` passes
+6. Frontend `npm run typecheck` passes
+7. Frontend `npm run build` passes
+8. File sizes are reduced: no API router > 500 lines, no service > 400 lines
+
+## Preconditions
+
+- Current `dev` branch is stable and all behavioral forward-ports are complete
+- All legacy `ToolConfig`/`ConfigFolder` code has been removed
+- Database migrations are at a single head

+- [ ] Phase 5: API router subpackages (tool, config, workspace, user, project, system)
+- [ ] Phase 6: Auth dependency refactor
+- [ ] Phase 7: Frontend reorganization
+- [ ] Phase 8: Integration and verification
+
+## Files Changed
+- `apps/api/src/services/docker.py` → deleted (split into package)
+- `apps/api/src/services/docker/__init__.py` — re-exports all public functions
+- `apps/api/src/services/docker/compose.py` — compose generation & commands
+- `apps/api/src/services/docker/container.py` — container runtime queries
+- `apps/api/src/services/docker/config_staging.py` — file staging into instances
+- `apps/api/src/services/docker/tunnel.py` — cloudflared tunnel lifecycle
+- `apps/api/src/services/tunnel.py` — thin backward-compat re-export wrapper
+
+## Notes
+- All backward-compatible imports preserved via __init__.py re-exports
+- `from src.services.docker import X` continues to work for all previously exported symbols
+- `from src.services.tunnel import X` continues to work via re-export wrapper
+- No behavior changes, pure structural refactor
