feat: enhance dev server URL handling and improve accessibility

- Added URL and URLSearchParams as readonly globals in ESLint configuration.
- Updated WorktreeActionsDropdown and WorktreeTab components to include aria-labels for better accessibility.
- Implemented error handling for dev server URL opening, ensuring only valid HTTP/HTTPS protocols are used and providing user feedback for errors.

These changes improve user experience and accessibility when interacting with the dev server functionality.
