Fix migrate.mjs exiting with code 1 after successful migration

client.end() in the finally block was throwing (postgres driver already
cleaned up connections internally during migrate()), causing an unhandled
rejection and exit code 1 despite the migration succeeding.

- Use explicit process.exit(0)/exit(1) instead of relying on implicit exit
- Wrap both client.end() calls with .catch(() => {}) to tolerate cleanup errors
- Add onnotice: () => {} to suppress noisy NOTICE messages (schema/table
  already exists) that are normal on every idempotent re-run
