WebAuthn challenge unicode-normalization tests

[Miracle656]

Background

WebAuthn challenges are bytes, but display names contain unicode that can be normalized differently (NFC vs NFD). Tests catch hash-mismatch bugs.

What to build

Tests that register with the same display name in NFC and NFD form, confirm both produce a deterministic credential ID, and confirm signing works after either form.

Key files

• sdk/tests/webauthn-normalization.test.ts (new)

Acceptance criteria

• NFC and NFD inputs converge
• Test runs in <5s

I'd love to take on this issue for you.

I know the unicode normalization hazard in WebAuthn well enough to write tests that confirm convergence rather than just the happy path.

Here's my plan:

• sdk/tests/webauthn-normalization.test.ts registering with NFC and NFD forms, asserting identical deterministic credential IDs
• Signing verified after registration with either form
• Suite completes under 5s

Ready to start immediately.
