Subject: [PATCH] test(repo): Prevent Python test bytecode drift

Set PYTHONDONTWRITEBYTECODE for the shared Python runner and the
root test-suite launcher so local test runs do not create __pycache__
artifacts inside skills.

This keeps npm run test deterministic and avoids false negatives in the
editorial bundle inventory checks.
