RustQueue 0.8.0

RustQueue 0.8.0 adds a production-shaped Kodo compatibility profile entirely on the RustQueue side. Upstream Kodo does not need to be modified.

Highlights

Discovery /nodes advertises three stable producer Gateway identities while /lookup continues to return the real Broker owners used by consumers.
The Gateway terminates the NSQ producer protocol, routes only to publish-ready Brokers, and retries another Broker only after an explicit pre-commit rejection. Ambiguous post-write failures are returned without an automatic replay.
The NSQ-compatible /stats response now includes the standard topic_name, channel_name, depth, client, and cumulative counter fields expected by Kodo.
Topic and Channel message, requeue, and timeout counters are durable and monotonic across restart, empty, and eviction.
Kodo's unauthenticated channel cleanup is disabled and fails closed. Administrative operations use RustQueue's authenticated native management flow.
The stable protocol/storage maximum is now 100 MiB. The Kodo profile accepts and validates Kodo's exact 104,857,500-byte application maximum.
Token rotation, drain and disk-pressure routing, rolling cutover, readiness fences, metrics, alerts, and Operator status handling are hardened.

Kodo compatibility remains opt-in with queue.kodoCompatibility.enabled=true.
The profile requires three schedulable Broker/Gateway nodes and an immutable image digest. Consult the Kubernetes operations guide for resource, network-policy, and cutover requirements.
Existing clusters must first roll the 0.8.0 Broker image and wait for Ready=True before enabling the Kodo profile or publishing messages above the previous limit.
After Gateway advertisement, restart every Kodo publisher and update producerRestartNonce. Broker maintenance remains blocked until the restart fence is confirmed.
Automatic Kodo channel cleanup must remain disabled.
Storage feature level 2 is a monotonic rollback floor after large records are written.
