chore: Fix all 246 TypeScript errors in UI

- Extended SetupAPI interface with 20+ missing methods for Cursor, Codex,
  OpenCode, Gemini, and Copilot CLI integrations
- Fixed WorktreeInfo type to include isCurrent and hasWorktree fields
- Added null checks for optional API properties across all hooks
- Fixed Feature type conflicts between @automaker/types and local definitions
- Added missing CLI status hooks for all providers
- Fixed type mismatches in mutation callbacks and event handlers
- Removed dead code referencing non-existent GlobalSettings properties
- Updated mock implementations in electron.ts for all new API methods
