feat: separate project settings from global settings

This PR introduces a new dedicated Project Settings screen accessible from
the sidebar, clearly separating project-specific settings from global
application settings.

- Added new route `/project-settings` with dedicated view
- Sidebar navigation item "Settings" in Tools section (Shift+S shortcut)
- Sidebar-based navigation matching global Settings pattern
- Sections: Identity, Worktrees, Theme, Danger Zone

**Moved to Project Settings:**
- Project name and icon customization
- Project-specific theme override
- Worktree isolation enable/disable (per-project override)
- Init script indicator visibility and auto-dismiss
- Delete branch by default preference
- Initialization script editor
- Delete project (Danger Zone)

**Remains in Global Settings:**
- Global theme (default for all projects)
- Global worktree isolation (default for new projects)
- Feature Defaults, Model Defaults
- API Keys, AI Providers, MCP Servers
- Terminal, Keyboard Shortcuts, Audio
- Account, Security, Developer settings

Both Theme and Worktree Isolation now follow a consistent override pattern:
1. Global Settings defines the default value
2. New projects inherit the global value
3. Project Settings can override for that specific project
4. Changing global setting doesn't affect projects with overrides

- Fixed: Changing global theme was incorrectly overwriting project themes
- Fixed: Project worktree setting not persisting across sessions
- Project settings now properly load from server on component mount

- Shell syntax editor: improved background contrast (bg-background)
- Shell syntax editor: removed distracting active line highlight
- Project Settings header matches Context/Memory views pattern

- `apps/ui/src/routes/project-settings.tsx`
- `apps/ui/src/components/views/project-settings-view/` (9 files)

- Global settings simplified (removed project-specific options)
- Sidebar navigation updated with project settings link
- App store: added project-specific useWorktrees state/actions
- Types: added projectSettings keyboard shortcut
- HTTP client: added missing project settings response fields
