All 3 doc files now list all 12 tools including rah_get_context and rah_update_edge. Fixed local dev path (was stdio-server.js, now index.js). Added "What to Expect" sections explaining proactive behavior. Removed "run app first" requirement since DB auto-creates. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
