0.2.2

• REPL now exits cleanly on EOF / Ctrl+D. Session stats and goodbye message still shown.
• DATABASE_URL handling improved. Empty env value no longer treated like valid DSN.
• PostgreSQL driver resolution fixed. Explicit --driver postgres no longer falls into unknown-driver path.
• Driver detection errors clearer. If DSN cannot be inferred, QRY now tells user to pass --driver.
• Non-SELECT SQL now shows execution result, including affected row count when available.
