Replace the hand-curated region groups with data-driven ones and make the region_groups ClickHouse table the single source of truth. - scripts/generate-region-groups.ts: offline generator — clusters regions by cross-region packet co-occurrence (min-share single-linkage) at two levels (broad "region" + tight "metro"), names clusters via `claude -p`, reconciles codes by member overlap so permalinks stay stable, and emits the region_groups seed. Migration 004 reseeded with the resulting 39 groups. - Groups are DB-sourced: getRegionGroups() (cached) feeds /api/regions and the dropdown/labels; filtering resolves a selector in SQL to a region (region = 'X') or a group (region IN / hasAny ... SELECT region_code FROM region_groups WHERE group_code = ...). No hardcoded membership in TS; resolveSelector removed. - Drop the TS<->SQL parity script (no membership left to sync); regionSql and the migration ALIAS are kept in sync by hand.
