kid break to dev
When a configured key has a kid, this now rejects every previously valid token that omits the header, although single-key verification intentionally accepted those tokens before this commit. Because moq-auth is a published 0.1.x package and this commit targets main, that behavioral compatibility break must be moved to dev rather than shipped as an additive feature on main; the equivalent JavaScript change should move with it.

Name lease::Producer as the re-check clock owner.
The phrase “consumer of a lease::Producer” can suggest that a consumer handle owns due(), update(), and failed(). These methods and the clock belong to Producer. The following paragraph repeats their behavior. Keep the method details there and remove the duplicate summary.

Await the .resolves assertion.
The assertion on Key.decode is not awaited. The test can finish before the promise settles. If decode then rejects or returns another payload, this test does not fail. This is the main positive case of the test, so it must be enforced.

🩺 Stability & Availability | 🟠 Major | ⚡ Quick win
Compute the first re-check with checked_add so a large revalidate cannot panic.
Clock::new computes tokio::time::Instant::now() + cadence, and this addition panics on overflow. cadence is grant.revalidate, which comes from the auth server's reply. If that reply carries a very large value (for example u64::MAX seconds), the following happens:
Producer::newpanics insideClient::connect.Producer::updatepanics while it holds theclockMutex. This poisons the Mutex, so every laterdue(),failed(), orimmediate()call panics on.expect("lease clock").
Treat a cadence that cannot be represented as "no scheduled re-check". The expires bound still ends the lease.

Preserve publish-capable roles when mapping future variants.
moq_net::Role is non-exhaustive. If a future variant permits publishing, this wildcard maps it to Subscriber, and Cluster::scope removes the publisher origin. The Tokio conversion uses the same mapping, so this affects both paths. Map unrecognized variants to None in both conversions; None is the documented bidirectional fallback.

Because moq_auth::Transport is public and lacks #[non_exhaustive], adding these variants makes downstream exhaustive matches fail to compile when updating the published 0.1.x crate. This is an API break independent of the already-reported kid behavior, so this main-targeted change needs to move to dev; the new serve::Keys::Set variant has the same compatibility problem.

When an embedder registers one of these gateway requests in the public session::Registry, operator commands such as moq auth sessions --transport rtmp and moq auth revalidate --transport webrtc fail with HTTP 400: rs/moq-relay/src/session.rs::parse_transport still accepts only quic, iroh, websocket, tcp, unix, and http. Add the three new wire values to that parser and its filter tests so gateway sessions can be selected and nudged by transport.

Lease clock ownership on the producer, role-scoped origins, and kid-consistent verification are justified by the security/stats consistency goal.

Gateway embedders duplicate the relay's authorization, origin scoping, and stats attribution. Their sessions can outlive a revoked or narrowed grant. Custom signed payloads also require a second JWT decoder, and the auth server cannot read a JWK Set.
