Evaluate codebase knowledge-graph plugins for Claude Code

CEO request (via video source): evaluate Understand-Anything (Lum1104) and Graphify (safishamsi) — two Claude Code plugins that convert a codebase into a queryable knowledge graph to (a) cut tokens during AI-assisted research and (b) give a human-explorable map of the repo.

See output/output.md for the full evaluation (composite 3.4, Accept with caveats — Graphify primary, Understand-Anything for onboarding/visualization).
