fix: adress pr comments

- Added validation to check if the specified worktree path exists before generating commit messages.
- Implemented a check to ensure the worktree path is a valid git repository by verifying the presence of the .git directory.
- Improved error handling by returning appropriate responses for invalid paths and non-git repositories.
