feat: Enhance issue management with batch processing and solution querying

- Updated issue loading process to create batches based on size (max 3 per batch).
- Removed semantic grouping in favor of simple size-based batching.
- Introduced a new command to batch query solutions for multiple issues.
- Improved solution loading to fetch all planned issues with bound solutions in a single call.
- Added detailed handling for multi-solution issues, including user selection for binding.
- Created a new workflow command for multi-agent development with documented progress and incremental iteration support.
- Added .gitignore for ace-tool directory to prevent unnecessary files from being tracked.
