This commit introduces a new feature for managing worktree initialization scripts, allowing users to configure and execute scripts upon worktree creation. Key changes include:
1. **New API Endpoints**: Added endpoints for getting, setting, and deleting init scripts.
2. **Worktree Routes**: Updated worktree routes to include init script handling.
3. **Init Script Service**: Created a service to execute the init scripts asynchronously, with support for cross-platform compatibility.
4. **UI Components**: Added UI components for displaying and editing init scripts, including a dedicated section in the settings view.
5. **Event Handling**: Implemented event handling for init script execution status, providing real-time feedback in the UI.
This enhancement improves the user experience by allowing automated setup processes for new worktrees, streamlining project workflows.
