Ping QiuandClaude Opus 4.6 3557ae283f feat: Phase 10 CP10-3 -- NVMe/TCP Tier 1 optimizations, WAL admission control, benchmark platform ...

CP10-3 Tier 1 optimizations (T1-T4):
- TCP_NODELAY + 256KB socket buffers on NVMe/TCP connections
- Response batching: all C2H data chunks + CapsuleResp in single flush
- Tiered buffer pool (4KB/64KB/256KB sync.Pool) for write payloads
- Configurable MaxH2CDataLength wiring through controller/IC/chunking

BUG-CP103-1: NVMe write retry with jittered backoff for transient WAL pressure
- writeWithRetry() with bounded backoff [50/200/800ms]
- throttleOnWALPressure() pre-write delay above 90% WAL usage
- WALPressureProvider interface + NVMeAdapter.WALPressure()

BUG-CP103-2: Volume-level WAL admission control
- WALAdmission with counting semaphore (max concurrent writers)
- Soft watermark (0.7): small delay to desynchronize herd
- Hard watermark (0.9): block until flusher drains
- Single-deadline budget shared across watermark wait + semaphore
- Close-aware during both watermark and semaphore waits
- Wired into BlockVol.WriteLBA() and Trim()

Benchmark platform enhancements:
- NVMe benchmark actions and scenarios (A/B, CW sweep, IOQ sweep)
- Database benchmark actions (SQLite, pgbench)
- K8s operator QA reconciler tests
- New testrunner scenarios for HA, fault injection, CSI lifecycle

Test counts: 213 NVMe + 625 engine + operator + testrunner tests, all passing.
