Closes#151
- Refactor spec-view.tsx from 1,230 lines to ~170 lines following folder-pattern.md
- Create unified CreateSpecDialog with all features from both dialogs:
- featureCount selector (20/50/100) - was missing in spec-view
- analyzeProject checkbox - was missing in sidebar
- Extract components: spec-header, spec-editor, spec-empty-state
- Extract hooks: use-spec-loading, use-spec-save, use-spec-generation
- Extract dialogs: create-spec-dialog, regenerate-spec-dialog
- Update sidebar to use new CreateSpecDialog with analyzeProject state
- Delete deprecated project-setup-dialog.tsx
