v1.11.16

Test suite

• Replaced the Docker-managed GizmoSQL test server with the new
  gizmosql PyPI package. The test
  fixture now starts the server as a subprocess via
  gizmosql.Server(...), which auto-picks a free port (enabling parallel
  pytest workers), guarantees client/server release parity, and drops the
  custom Docker log-poller. Local development no longer requires Docker
  Desktop running for the GizmoSQL server itself.
• Refactored test_external.py's MinIO sidecar to bind to
  localhost:9000 instead of routing through a user-defined Docker
  bridge network with container aliases — the GizmoSQL subprocess is now
  on the host, so the network gymnastics are no longer needed.
• Removed test.env and the pytest-dotenv dependency; test fixtures
  construct connection details directly from the Server object.

Dependency updates

• Bumped dbt-core to ~=1.11.9, dbt-common to ~=1.38.0, and
  dbt-adapters to ~=1.23.0.
• Bumped adbc-driver-gizmosql minimum to >=1.1.6.
• Added gizmosql as a dev dependency (the new test-fixture driver);
  docker is retained for the MinIO sidecar still used by
  test_external.py.
