feat: Add run init script functionality for worktrees

This commit introduces the ability to run initialization scripts for worktrees, enhancing the setup process. Key changes include:

1. **New API Endpoint**: Added a POST endpoint to run the init script for a specified worktree.
2. **Worktree Routes**: Updated worktree routes to include the new run init script handler.
3. **Init Script Service**: Enhanced the Init Script Service to support running scripts asynchronously and handling errors.
4. **UI Updates**: Added UI components to check for the existence of init scripts and trigger their execution, providing user feedback through toast notifications.
5. **Event Handling**: Implemented event handling for init script execution status, allowing real-time updates in the UI.

This feature streamlines the workflow for users by automating the execution of setup scripts, improving overall project management.
