Persistent transclusion context for Information Spaces.

This package extends the existing TransclusionContext with:
- Database persistence for context state
- Cross-space reference resolution
- Reference graph for dependency tracking
- Variable scope layers (space, document, request)
- Event-driven cache invalidation
