feat: add PR build check workflow and enhance feature management

- Introduced a new GitHub Actions workflow for PR build checks to ensure code quality and consistency.
- Updated `analysis-view.tsx`, `interview-view.tsx`, and `setup-view.tsx` to incorporate a new `Feature` type for better feature management.
- Refactored various components to improve code readability and maintainability.
- Adjusted type imports in `delete-project-dialog.tsx` and `settings-navigation.tsx` for consistency.
- Enhanced project initialization logic in `project-init.ts` to ensure proper type handling.
- Updated Electron API types in `electron.d.ts` for better clarity and functionality.
