PR #9931 ("feat(google-workspace): add --from flag for custom sender display name")
accidentally removed the required_credential_files frontmatter block that tells
hermes to bind-mount google_token.json and google_client_secret.json into Docker
and Modal remote terminals before running setup.py.
Without this header the credential files are never registered in the session-scoped
ContextVar, so get_credential_file_mounts() returns an empty list at container
creation time and the OAuth files are invisible inside the sandbox.
