WebAuthn attestation trust check: parse attestationObject fmt/attStmt, verify packed and fido-u2f self-attestation signatures, verify x5c leaf certificate signatures when the crypto backend is present, echo AAGUID and credential material, and state the trust level (FIDO MDS not configured; never overstated).
