Phase 1: Migrate from SQLite to PostgreSQL

- Provisioned PostgreSQL 16 droplet (2vCPU/4GB) on DO
- Converted Drizzle ORM from better-sqlite3 to node-postgres
- Updated schema to use pgTable, serial, timestamp
- Added initDb() startup function for table creation
- Configured connection pooling (max 20, idle timeout)
- Removed better-sqlite3 dependency
- Deployed and verified: auth create/read works on PostgreSQL
- DB: gammanexus@gammanexus-db (10.136.95.120 private network)
