feat: enhance auto mode service and UI components for branch handling and verification

- Added a new function to retrieve the current branch name in the auto mode service, improving branch management.
- Updated the `getRunningCountForWorktree` method to utilize the current branch name for accurate feature counting.
- Modified UI components to include a toggle for skipping verification in auto mode, enhancing user control.
- Refactored various hooks and components to ensure consistent handling of branch names across the application.
- Introduced a new utility file for string operations, providing common functions for text manipulation.
