docs: update reorganize-long-files spec to include CSS reorganization

Add Phase 2 (CSS Reorganization) covering:
- Restore styles/ directory (tokens, global, utilities, syntax-highlight)
- Restore styles/pages/*.css for page-specific styles
- Restore 11 component CSS modules from monolithic styles.css
- Delete styles.css after extraction

Shift frontend page extraction phases to 3-7.
Add visual regression checks to integration phase.

Quality gates unchanged: tsc, build, py_compile, file size limits

+## Why
+
+After the backend-frontend refactoring (commits `0591b00` through `8c7affc`), the codebase gained proper directory structure but several files grew into monoliths. The `main` branch (pre-refactor baseline at `5ed5e1c`) kept pages thin by delegating to extracted components. On `dev`, new features were added inline, causing pages and routers to absorb responsibilities that belong in components or services.
+
+### Problem Files (Frontend)
+
+| File | Lines | Problem |
+|------|-------|---------|
+| `pages/ToolWorkshopPage.tsx` | **1,269** | Merged 3 tab components inline (ToolTypes, ToolConfigs, ConfigFolders) |
+| `pages/ConfigProfilesPage.tsx` | **1,611** | List, detail, edit, create, and mobile views all in one file |
+| `pages/TerminalPage.tsx` | **571** | Session tabs, keyboard shortcuts, fullscreen, mobile overlay, special keys all inline |
+| `pages/RepoWorkspacePage.tsx` | **505** | File editor, git toolbar, workspace header, sidebar logic inline |
+| `pages/SettingsPage.tsx` | **284** | Settings nav + multiple setting sections inline |
+| `pages/SshKeysPage.tsx` | **277** | List and create inline |
+
+### Problem Files (Backend)
+
+| File | Lines | Problem |
+|------|-------|---------|
+| `api/tool/tool_instances.py` | **2,900** | CRUD, Docker lifecycle, WebSocket proxy, terminal sessions, instance proxy all in one router |
+| `api/project/git_repositories.py` | **1,588** | HTTP endpoints mixed with git command orchestration |
+| `api/config/config_profiles.py` | **842** | CRUD + validation + resolver + mount/include management |
+
+### What `main` Did Differently
+
+`main` at `5ed5e1c`:
+- `ToolWorkshopPage.tsx` = **77 lines** (just a tab switcher, tabs imported from `features/tool-workshop/`)
+- `TerminalPage.tsx` = **38 lines** (just a wrapper around `TerminalComponent`)
+- `api/tool_instances.py` = **284 lines** (HTTP endpoints only)
+- `api/terminal.py` = **158 lines** (separate WebSocket router)
+
+## What Changes
+
+Restore the **thin-page / thin-router / fat-component** pattern from `main`, adapted to current `dev` features:
+
+1. **Frontend page extraction** — Split monolithic pages into:
+   - Page shell (orchestrator, 50-150 lines)
+   - Tab components (for tabbed pages)
+   - List / Detail / Edit / Create components (for CRUD pages)
+   - Mobile-specific views (extracted, not inline)
+
+2. **Backend router slimming** — Split `tool_instances.py` into:
+   - `tool_instances.py` — CRUD endpoints only
+   - `tool_lifecycle.py` — Start/stop/restart/delete logic
+   - Move terminal WebSocket back to dedicated `terminal.py`
+
+3. **Git repository router** — Extract git command orchestration into `services/git/`
+
+## Capabilities
+
+### New Capabilities
+- None (pure structural refactor)
+
+### Modified Capabilities
+- `frontend-structure`: Pages become orchestrators; components carry the UI logic
+- `backend-structure`: Routers become HTTP-only; services carry business logic
+
+## Impact
+
+- **Frontend**: New `features/tool-workshop/` tab components, new `features/config-profiles/` components, `features/terminal/` session manager, etc.
+- **Backend**: New `api/tool/tool_lifecycle.py`, `api/tool/terminal.py`, slimmer `api/tool/tool_instances.py`
+- **Tests**: Test files may need import path updates (component moved → test follows)
+
+## Exclusions (Already Done / Out of Scope)
+
+- Directory structure already exists (`features/`, `services/`, etc.)
+- Schema extraction already done (`schemas/` subpackages)
+- Model subpackages already done (`models/` subpackages)
+- API router subpackages already done (`api/tool/`, `api/project/`, etc.)
+- File naming already done (kebab-case APIs, PascalCase pages)
+- No behavioral changes to any endpoint or UI flow
+- No database schema changes
+- No new features

+## Scope
+
+This change is a **pure structural refactoring** to split monolithic pages and routers into focused components and services. No API contracts, database schemas, or user-facing behaviors change.
+
+### In Scope
+
+#### 1. Frontend Page Extraction
+
+Split the following pages into a thin page shell + extracted components:
+
+**`pages/ToolWorkshopPage.tsx` (1,269 → ~80 lines)**
+- Extract `ToolTypesTab` → `components/features/tool-workshop/ToolTypesTab.tsx`
+- Extract `ToolConfigsTab` → `components/features/tool-workshop/ToolConfigsTab.tsx`
+- Extract `ConfigFoldersTab` → `components/features/tool-workshop/ConfigFoldersTab.tsx`
+- Page becomes: tab switcher only, imports the 3 tabs
+
+**`pages/ConfigProfilesPage.tsx` (1,611 → ~80 lines)**
+- Extract `ConfigProfileListView` → list view + mobile list view
+- Extract `ConfigProfileDetailView` → detail view with edit toggle
+- Extract `ConfigProfileEditForm` → edit/create form
+- Extract `ConfigProfileMobileView` → mobile view state machine wrapper
+- Page becomes: router between list/detail/edit views
+
+**`pages/TerminalPage.tsx` (571 → ~80 lines)**
+- Extract `TerminalSessionManager` → session tabs + auto-create logic
+- Extract `TerminalKeyboardShortcuts` → shortcut handler hook (already exists, just use it)
+- Extract `MobileTerminalOverlay` → mobile overlay toolbar + tabs
+- Page becomes: choose between desktop (`TerminalComponent` + `TerminalSessionTabs`) and mobile (`MobileTerminalOverlay` + `TerminalComponent`) wrappers
+
+**`pages/SettingsPage.tsx` (284 → ~80 lines)**
+- Extract `SettingsNavigation` → settings nav sidebar
+- Extract `GeneralSettingsTab`, `SSHKeysTab` (already separate pages, but move sections into components if inline)
+- Page becomes: nav + `<Outlet>` for nested routes
+
+**`pages/SshKeysPage.tsx` (277 → ~80 lines)**
+- Extract `SSHKeyList` → list with actions
+- Extract `SSHKeyCreateForm` → create form
+- Page becomes: layout wrapper + conditionally render list or form
+
+**`pages/RepoWorkspacePage.tsx` (505 → ~150 lines)**
+- Extract `WorkspaceLayout` → sidebar + main content layout
+- Page becomes: data loader + layout wrapper
+
+**`pages/ProjectsPage.tsx` (433 → ~100 lines)**
+- Extract `ProjectList` → list with cards
+- Extract `ProjectCreateDialog` → create form in dialog
+- Extract `ProjectEditDialog` → edit form in dialog
+- Page becomes: data loader + layout + dialog state manager
+
+#### 2. CSS Reorganization
+
+**`styles.css` (5,683 lines → deleted)**
+- Restore `styles/` directory with extracted files:
+  - `styles/tokens.css` — CSS custom properties (colors, spacing, typography)
+  - `styles/global.css` — global reset, body, shell layout
+  - `styles/utilities.css` — utility classes (.stack, .card, .muted, etc.)
+  - `styles/syntax-highlight.css` — code highlighting
+- Restore `styles/pages/*.css` — page-specific styles:
+  - `styles/pages/dashboard.css`
+  - `styles/pages/projects.css`
+  - `styles/pages/sessions.css`
+  - `styles/pages/settings.css`
+  - `styles/pages/ssh-keys.css`
+  - `styles/pages/git-history.css`
+  - `styles/pages/repo-workspace.css`
+- Restore component CSS modules:
+  - `components/features/terminal/TerminalComponent.module.css`
+  - `components/features/git/GitToolbar.module.css`
+  - `components/features/git/CommitDialog.module.css`
+  - `components/features/git/MergeDialog.module.css`
+  - `components/features/git/FileEditor.module.css`
+  - `components/features/git/FileBrowser.module.css`
+  - `components/features/git/FileViewer.module.css`
+  - `components/features/git/CommitPanel.module.css`
+  - `components/features/session/InstanceList.module.css`
+  - `components/features/settings/SettingsTabLayout.module.css`
+  - `components/layout/AppShell.module.css`
+- Update all component imports to use `import styles from './ComponentName.module.css'`
+- Update `main.tsx` to import `styles/tokens.css`, `styles/global.css`, `styles/utilities.css`, `styles/syntax-highlight.css`
+- Update each page to import its `styles/pages/*.css`
+- Delete monolithic `styles.css`
+
+#### 3. Backend Router Slimming
+
+**`api/tool/tool_instances.py` (2,900 → ~300 lines)**
+- Extract terminal WebSocket handlers → `api/tool/terminal.py` (~400 lines)
+- Extract instance lifecycle (create/start/stop/delete/restart) → `api/tool/tool_lifecycle.py` (~600 lines)
+- Keep in `tool_instances.py`: CRUD endpoints (GET list, GET detail, POST, PATCH, DELETE) + instance proxy endpoint
+
+**`api/project/git_repositories.py` (1,588 → ~300 lines)**
+- Extract git command orchestration into `services/git/operations.py`
+- Router keeps: auth, parameter validation, response building, error handling
+- Service functions: `clone_repo`, `fetch_repo`, `pull_repo`, `push_repo`, `merge_repo`, etc.
+
+**`api/config/config_profiles.py` (842 → ~200 lines)**
+- Extract resolver orchestration into `services/config/resolver_service.py`
+- Extract CRUD helpers into `services/config/crud_service.py`
+- Router keeps: endpoint definitions, auth, input validation
+
+### 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)
+- Moving existing `features/` components (already organized)
+- Renaming files (naming already done)
+- Changing any CSS rules (only moving them)
+
+## Acceptance Criteria
+
+1. All pages ≤ 150 lines (except `RepoWorkspacePage` which may stay at ~150)
+2. All API routers ≤ 400 lines
+3. No monolithic `styles.css` — all CSS in `styles/` directory or `.module.css` files
+4. All existing tests pass without modification (behavior unchanged)
+5. All existing API endpoints return identical responses
+6. Frontend `npm run typecheck` passes
+7. Frontend `npm run build` passes
+8. Backend `py_compile` passes on all files
+9. No import errors in browser console
+10. File count increases (more files, smaller files)
+
+## Preconditions
+
+- `dev` branch is stable (all fixes from this session are committed)
+- Backend compiles (`py_compile` pass)
+- Frontend typechecks and builds (`tsc`, `vite build` pass)
+- Current tests pass (or known failures are documented)
