Updates handoff/progress/todos to reflect that M2 is committed and
visually verified, and documents the three bugs found (and fixed)
along the way: the memory_graph_routes.py owner-scoping mismatch,
the detail panel's stuck `hidden` class, and search leaving stale
selection-highlight opacity over its own matches.
Repo-wide analysis of frontend/backend/DB/memory/ChromaDB/auth/Docker/
testing conventions, plus the accepted design (architecture, API, UI,
performance, security, migration/rollback, testing strategy) for the
Memory Graph View feature.
