feat(targets): add an opt-in NATS JetStream publish path for the notify and audit targets
The NATS notify and audit targets publish through NATS Core, which returns
before the server has durably accepted the message. A broker restart or a
connection drop between the publish and the flush loses the event, even though
the send queue has already cleared it, and no acknowledgement gates that clear.
An opt-in JetStream publish path clears a queued event only after the server
returns a durable PublishAck, so delivery is at-least-once across a broker
restart or a reconnect. It applies to both the notify and audit NATS targets, is
off by default, and is byte-identical to the NATS Core path when disabled.
The path includes durable store-and-forward, a stable dedup id sent as the
Nats-Msg-Id header so a replayed event is collapsed by the stream duplicate
window, pre-flight stream validation, and a bounded failed-events store for
terminally-failed and retry-exhausted events. Three configuration keys per
target select it: JETSTREAM_ENABLE, JETSTREAM_STREAM_NAME, and
JETSTREAM_ACK_TIMEOUT_SECS, under the RUSTFS_NOTIFY_NATS_ and RUSTFS_AUDIT_NATS_
prefixes.
The on-disk batch filename separator changes from colon to underscore so
batch names are valid on Windows filesystems, with transparent read-back
of files written under the previous separator. The migration affects the
shared queue store for every target type and lands with this feature
because the store gains its first Windows-exercised paths here.

Address a batch of correctness/security audit findings in the messaging
notification backends (mqtt/nats/kafka/amqp/redis/pulsar/webhook).
MQTT (backlog#971): wait for broker acknowledgement via publish_tracked +
wait_completion_async (PUBACK/PUBCOMP for QoS>=1, flush for QoS0) with a
30s timeout before reporting success, instead of treating the enqueue as
delivered. Replace substring error matching with typed ClientError /
PublishNoticeError classification.
NATS (backlog#971, #973, #983): flush() after publish to confirm the broker
received the message before the durable copy is deleted; classify publish
and flush failures by typed error kind; warn when credentials are sent
without TLS.
Kafka (backlog#973, #983): use Error::is_retriable() so transient broker
states (NotLeaderForPartition, LeaderNotAvailable, RequestTimedOut, ...) are
retried instead of dropped as permanent; add a bucket/object message key for
per-object partition ordering; build the producer without holding the cache
lock across the connect await.
AMQP (backlog#973, #980): classify permanent broker protocol errors
(404/403/406, NOT_ALLOWED, ...) as request-level errors rather than
connectivity errors to avoid reconnect storms; bound publish and
publisher-confirm waits with a timeout; check is_enabled in is_active; run
full close() cleanup even when the broker close fails; warn when
mandatory=false may silently drop unroutable messages.
Redis (backlog#982): warn when PUBLISH reaches 0 subscribers; reuse the
cached ConnectionManager for health probes instead of a fresh handshake;
warn when tls_allow_insecure disables certificate verification.
Pulsar (backlog#983): replace std::sync::Mutex + unwrap with parking_lot
Mutex so a panic while holding the guard cannot poison later accesses.
Webhook (backlog#983): drain the response body so the connection can be
reused (keep-alive). The #974 redirect-follow SSRF fix already landed.
