Re: [webauthn] Proposal: Scoped Attestation Privacy + Practical CBOR Size Guidance (WebAuthn L3) (#2390)

Reference WPT-style tests (WARN-only, non-normative):

- webauthn/scoped-attestation-privacy.https.sub.html
- webauthn/resources/scoped-attestation-subframe.sub.html
- webauthn/attestation-size-guidance.https.html
- webauthn/cbor-deterministic-guidance.https.html

Notes:
- WARN-only diagnostics (no conformance failures).
- Cross-origin comparison follows the standard WPT alt-host subframe pattern.
