-- =============================================================================
-- VIBN fs_* tables + agent_sessions migration
-- Run once against the production Coolify Postgres database.
--
-- These tables back the live app (fs_ prefix = "Firestore-shaped" flexible
-- JSONB rows that replaced the original Firebase collections).
--
-- Safe to re-run — all statements use IF NOT EXISTS / ON CONFLICT.
-- =============================================================================

-- Enable uuid support (safe no-op if already enabled)
