Codex review

The PR has a definite import-time syntax regression in one cookbook example and a release workflow ordering issue that can publish/tag ten-moss before all supported Python versions pass.

BLOCKING ```python
class MossListIndexesInput(BaseModel):
"""Input schema for MossListIndexesTool."""
# No input needed

Removing the `pass` leaves this class with no executable body, so the module raises `IndentationError` on import. Restore `pass` (or use `...`) under the comment.
