662b2e0d87 feat(consumers): add PriorityGroupManager and PullConsumer timeout/compiled filters (C5+C6) 2026-02-24 15:11:30 -05:00

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)

3e972f217e feat: add FileStore 6-way permutation tests (Go testFileStoreAllPermutations parity) 
Port 20 tests across the {NoCipher, ChaCha, Aes} x {NoCompression, S2Compression}
matrix from Go's testFileStoreAllPermutations (filestore_test.go:55), yielding 120
total Theory executions in FileStorePermutationTests.cs.

Also fix PushFrame.Subject property missing compilation error that was blocking
the test build (JetStreamConsumerDeliveryEdgeTests.cs:119).
