Syv nye API-endepunkter for kunnskapsgrafen: Entities: - GET/POST /api/entities — list, søk (name+aliases), filtrer på type - GET/PATCH/DELETE /api/entities/:id — hent (m/edge_count), oppdater, slett - GET /api/entities/:id/edges — relasjoner med retningsfilter Graf: - POST /api/graph/edges — opprett relasjon (upsert) - DELETE /api/graph/edges/:id — slett relasjon - GET /api/graph/search — fulltekstsøk (entiteter + transkripsjoner FTS) - GET /api/graph/traverse/:nodeId — recursive CTE, D3.js/Vis.js-format Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
