refactor: update all imports to use shared packages

- Updated 150+ files to import from @automaker/* packages
- Server imports now use @automaker/utils, @automaker/platform, @automaker/types, @automaker/model-resolver, @automaker/dependency-resolver, @automaker/git-utils
- UI imports now use @automaker/dependency-resolver and @automaker/types
- Deleted duplicate dependency-resolver files (222 lines eliminated)
- Updated dependency-resolver to use ES modules for Vite compatibility
- Added type annotation fix in auto-mode-service.ts
- Updated feature-loader to re-export Feature type from @automaker/types
- Both server and UI builds successfully verified

Phase 1 of server refactoring complete.
