Fix LeafNodeManager.StartAsync to launch solicited connections for RemoteLeaves
(config-file-parsed remotes) in addition to the programmatic Remotes list, and
update ParseEndpoint to handle nats-leaf:// scheme URLs. Add LeafNodeFixture
that polls /leafz for connection readiness and three E2E tests covering
hub→leaf delivery, leaf→hub delivery, and subject-scoped propagation.
- GatewayFixture: polls /gatewayz monitoring endpoint until both servers
report num_gateways >= 1, replacing Task.Delay with proper synchronization
- GatewayTests: two tests covering cross-gateway delivery and interest-only
no-delivery behaviour, using double PingAsync() instead of Task.Delay
- LeafNodeTests: replace Task.Delay(500) with sub.PingAsync()+pub.PingAsync()
to properly fence subscription propagation without timing dependencies
- Fix GatewayManager.StartAsync to read remotes from RemoteGateways (config-
parsed) in addition to the legacy Remotes list, enabling config-file-driven
outbound gateway connections
Adds 8 new E2E tests to JetStreamTests.cs (tests 11-18) covering push
consumer config, AckNone/AckAll policies, Interest/WorkQueue retention,
ordered consumers, mirror streams, and source streams.
Fixes three server gaps exposed by the new tests: mirror JSON parsing
(deliver_subject and mirror object fields were silently ignored in stream
and consumer API handlers), and deliver_subject omitted from consumer
info wire format. Also fixes ShutdownDrainTests to use TaskCompletionSource
on ConnectionDisconnected instead of a Task.Delay poll loop.
Replace Task.Delay polling with PeriodicTimer in NatsServerProcess readiness
checks and extend StartAsync to also TCP-poll the monitor port when enabled,
so MonitorServerFixture is guaranteed ready before tests run.

unknown string fallback, and sort ordering for key fields.
Go reference: server/monitor_sort_opts.go, server/monitor.go Connz().
Replace ConcurrentQueue<ClosedClient> with ClosedConnectionRingBuffer — a
fixed-size ring buffer that overwrites oldest entries when full, eliminating
the manual dequeue-to-cap loop. Adds TotalClosed lifetime counter, GetRecent(),
and Clear(). Wires the ring buffer into NatsServer including capacity resize
on config reload. Adds 10 unit tests covering capacity, ordering, wrapping,

layer for account-scoped filtering and pagination that mirrors the Go
server's /connz ?acc= query-parameter behaviour. Ten new tests in
ConnzAccountFilterTests.cs cover FilterByAccount (match, no-match,
case-insensitive), ConnzFilterOptions.Parse (acc param, defaults,
offset/limit), and ApplyFilters (account filter, offset, limit,
no-filter pass-through).
