feat(spaces): implement Phase 5 Directory Sync Mode
Implements directory synchronization for Information Spaces: - SpaceDirectoryExporter: Export space to directory structure - Multiple variants: flat, hierarchical, by_path - Manifest generation for reimport - Incremental export (skip unchanged files) - Metadata file export - IncrementalExporter for change detection - DirectorySpaceImporter: Import directory content into space - Recursive directory scanning - Multiple file pattern support - Conflict detection with strategies (skip/overwrite/rename) - Manifest-based import for intelligent reimport - Structure preservation in space paths - BidirectionalSyncCoordinator: Two-way sync with conflict detection - Sync directions: space-to-directory, directory-to-space, bidirectional - Conflict resolution strategies: space_wins, directory_wins, newer_wins, manual, skip - Dry-run mode for preview - Orphan cleanup option - Event emission for progress tracking 45 unit tests covering all sync components.
