Critical: AGENTS.md missing YAML frontmatter (Update overrides manual fixes)

The 'agents/AGENTS.md' file is currently missing the mandatory YAML frontmatter required by the Gemini CLI ExtensionManager. This results in a failure to load the agent: 'Invalid agent definition: Missing mandatory YAML frontmatter'.

This issue was previously noted in #79 and a fix was proposed in PR #78 over a month ago, but both remain unmerged.

Why this is urgent: Users who manually patch their local 'AGENTS.md' file to get the extension working have their fixes overwritten every time they run 'gemini extensions update huggingface-skills', pulling the broken version from the repository and breaking the installation again.

Please merge #78 to resolve this persistent issue for all users.
