Module credential 

WebAuthn credential descriptor and protocol DTOs (options, responses, results).

This module is storage-free. It defines the WebauthnCredential record (including the sign-count state that callers must persist) and the JSON wire structures exchanged with the browser. Persisting, looking up, and updating credentials is the integrator’s job; see the crate-level documentation for the recommended storage contract.
