55de052009 feat(consumer): add PriorityQueue-based RedeliveryTracker overloads 
Add new constructor, Schedule(DateTimeOffset), GetDue(DateTimeOffset),
IncrementDeliveryCount, IsMaxDeliveries(), and GetBackoffDelay() to
RedeliveryTracker without breaking existing API. Uses PriorityQueue<ulong,
DateTimeOffset> for deadline-ordered dispatch mirroring Go consumer.go rdq.

1e942c6547 feat: add consumer lifecycle, pause, replay & priority tests (Task 15) 
Port Go consumer_test.go and jetstream_test.go consumer lifecycle tests.
Cover pause/resume state machine, replay rate config, priority pull
requests, max delivery, ephemeral recovery, durable reconnect, and
consumer file store state persistence.

49 new tests ported from consumer_test.go and jetstream_test.go.

a9967d3077 test(parity): port consumer pull queue & filter tests (T14) + DB update 
Port 48 Go parity tests from TestJetStreamConsumerPull* and related
functions in jetstream_consumer_test.go to unit-level .NET tests.

Enhancements to PullConsumerEngine:
- MaxBytes enforcement in FetchAsync loop (stops delivery when budget exceeded)
- PullRequestWaitQueue with priority-ordered stable enqueue and popAndRequeue
  round-robin semantics within same-priority groups
- PullWaitingRequest record with Priority, RemainingBatch, Reply fields

Enhancements to ConsumerConfig:
- MaxWaiting, MaxRequestBatch, MaxRequestMaxBytes, MaxRequestExpiresMs

New tests (51 total in ConsumerPullQueueTests.cs):
- Pull MaxAckPending enforcement, FIFO delivery, one-shot semantics
- Pull timeout (ExpiresMs), NoWait behavior, MaxBytes byte budget
- Three-filter and multi-filter subject filtering, filter update
- WaitQueue priority ordering and popAndRequeue round-robin
- Pending count tracking, ack floor advancement, redelivery
- DeliverPolicy Last/LastPerSubject/ByStartTime with filters
- ConsumerIsFiltered detection, overlapping subject filters

DB: 37 Go tests mapped → ConsumerPullQueueTests.cs (1,386 total mapped)

579063dabd test(parity): port 373 Go tests across protocol and services subsystems (C11+E15) 
Protocol (C11):
- ClientProtocolGoParityTests: 45 tests (header stripping, tracing, limits, NRG)
- ConsumerGoParityTests: 60 tests (filters, actions, pinned, priority groups)
- JetStreamGoParityTests: 38 tests (stream CRUD, purge, mirror, retention)

Services (E15):
- MqttGoParityTests: 65 tests (packet parsing, QoS, retained, sessions)
- WsGoParityTests: 58 tests (compression, JWT auth, frame encoding)
- EventGoParityTests: 56 tests (event DTOs, serialization, health checks)
- AccountGoParityTests: 28 tests (route mapping, system account, limits)
- MonitorGoParityTests: 23 tests (connz filtering, pagination, sort)

DB: 1,148/2,937 mapped (39.1%), up from 1,012 (34.5%)

612b15c781 feat: add PushConsumer delivery loop and RedeliveryTracker (C3+C4) 
C3 – PushConsumerEngine delivery dispatch:
- Add DeliverSubject property (mirrors consumer.go:1131 dsubj field)
- Add StartDeliveryLoop / StopDeliveryLoop: background Task that drains
  ConsumerHandle.PushFrames and calls a sendMessage delegate per frame
- Delivery loop honours AvailableAtUtc for rate-limiting (consumer.go:5120)
- Data frames: HMSG headers Nats-Sequence, Nats-Time-Stamp, Nats-Subject
  (stream.go:586 JSSequence / JSTimeStamp / JSSubject constants)
- Flow-control frames: "NATS/1.0 100 FlowControl Request" (consumer.go:5501)
- Heartbeat frames: "NATS/1.0 100 Idle Heartbeat" (consumer.go:5222)
- Add DeliverSubject field to ConsumerConfig (consumer.go:115)

C4 – RedeliveryTracker with backoff schedules:
- Schedule(seq, deliveryCount, ackWaitMs): computes deadline using backoff
  array indexed by (deliveryCount-1), clamped at last entry (consumer.go:5540)
- GetDue(): returns sequences whose deadline has passed
- Acknowledge(seq): removes sequence from tracking
- IsMaxDeliveries(seq, maxDeliver): checks threshold for drop decision
- Empty backoff array falls back to ackWaitMs

Tests: 7 PushConsumerDelivery tests + 10 RedeliveryTracker tests (17 total)
