Replace the planner's Overpass proxy with a self-hosted POI index: - map-core POI categories become structured tag selectors (single source of truth) + osmium filter / classification helpers - planner.pois PostGIS table (centroid points, GiST + category indexes) - /api/pois serving route (session + same-origin + rate limit, 100 cap) - lib/pois.ts client (renamed from overpass.ts; GET, quantized bbox) - metrics: poi_api_requests_total + DB-collected index rows/age gauges; drop overpass_* metrics - remove /api/overpass proxy + dead OVERPASS_URLS on the planner service (Journal surface backfill still uses it via code default) Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
