gsxdsm 27cb2d2621 FN-8921: add deterministic knowledge graph tooling

Add a committable, provenance-tagged knowledge graph layer with CLI generation and query support.

- Extract TypeScript, Markdown, and FNXC knowledge into deterministic graph nodes and edges.
- Persist recoverable graph artifacts outside ignored Fusion state and expose build/query CLI commands.
- Document configuration and add core and CLI coverage for graph structure, serialization, and recovery.
