Catalog

Get the host-compat catalog

The versioned host-compatibility catalog backing mcpjam compat verdicts. Public and unauthenticated: static host facts and creation config with no project or user scope. Always returns a catalog — source is live when the backend publish was reachable and bundled when serving the SDK's built-in fallback.
