refactor(auto-mode): enhance feature retrieval logic in facade and global service

- Replaced synchronous feature retrieval with asynchronous logic in both AutoModeServiceFacade and GlobalAutoModeService.
- Updated filtering logic to resolve the primary branch name for main worktrees, improving accuracy in feature status checks.
- This change enhances the responsiveness and correctness of feature handling in auto mode operations.
