feat: enhance UI components and branch management

- Added new RadioGroup and Switch components for better UI interaction.
- Introduced BranchSelector for improved branch selection in feature dialogs.
- Updated Autocomplete and BranchAutocomplete components to handle error states.
- Refactored feature management to archive verified features instead of deleting them.
- Enhanced worktree handling by removing worktreePath from features, relying on branchName instead.
- Improved auto mode functionality by integrating branch management and worktree updates.
- Cleaned up unused code and optimized existing logic for better performance.
