fix: update compose submodule for Matrix bridge deps + persistent venv

Updates assets/compose submodule to 8adbbf0 (compose fix/matrix-bridge-deps).

Compose commit adds:
- uv pip install openai mautrix[encryption] to hermes entrypoint
- Persistent venv volume at /opt/hermes/.venv
- Empty-volume first-boot handling (venv recreation)

This ensures Matrix bridge dependencies survive container recreation.
