feat: Add batch deletion support (bd-127)
- Add DeleteIssues() method in sqlite.go for atomic batch deletion - Support multiple issue IDs as arguments or from file - Add --from-file flag to read IDs from file (supports comments) - Add --dry-run mode for safe preview without deleting - Add --cascade flag for recursive deletion of dependents - Add --force flag to orphan dependents instead of failing - Pre-collect connected issues before deletion for text reference updates - Add orphan deduplication to prevent duplicate IDs - Add rows.Err() checks in all row iteration loops - Full transaction safety - all deletions succeed or none do - Comprehensive statistics tracking (deleted, dependencies, labels, events) - Update README and CHANGELOG with batch deletion docs Fixed critical code review issues: - Dry-run mode now properly uses dryRun parameter instead of deleting data - Text references are pre-collected before deletion so they update correctly - Added orphan deduplication and error checks - Updated defer rollback pattern per Go best practices
