Use /gsd:map-codebase as a periodic resync tool

[manaskhuman]

While using GSD across multiple AI tools (Claude, Antigravity, etc.), sometimes code changes happen outside the GSD workflow.

Would it make sense to support /gsd:map-codebase as a periodic resync mechanism?

Example workflow:

External AI or manual edits modify the codebase

Run /gsd:map-codebase

GSD re-analyzes architecture and updates its understanding

This would help keep GSD aligned with the real codebase when working in mixed environments where not all changes go through /gsd:execute-phase.

Potentially this could even evolve into something like /gsd:sync-codebase that detects git changes and updates planning context.

Curious if this aligns with the intended use of map-codebase.
