feat: enhance auto mode functionality with worktree support

- Updated auto mode handlers to support branch-specific operations, allowing for better management of features across different worktrees.
- Introduced normalization of branch names to handle undefined values gracefully.
- Enhanced status and response messages to reflect the current worktree context.
- Updated the auto mode service to manage state and concurrency settings per worktree, improving user experience and flexibility.
- Added UI elements to display current max concurrency for auto mode in both board and mobile views.

This update aims to streamline the auto mode experience, making it more intuitive for users working with multiple branches and worktrees.
