feat: enhance PR handling and UI integration for worktrees

- Added a new route for fetching PR info, allowing users to retrieve details about existing pull requests associated with worktrees.
- Updated the create PR handler to store metadata for existing PRs and handle cases where a PR already exists.
- Enhanced the UI components to display PR information, including a new button to address PR comments directly from the worktree panel.
- Improved the overall user experience by integrating PR state indicators and ensuring seamless interaction with the GitHub CLI for PR management.
