feat: CP10B-1 NVMe/TCP RX/TX split + CP10B-2 bench/profiling fixes
RX/TX split: rxLoop reads PDUs, txLoop writes responses via respCh.
Handlers refactored to void + enqueueResponse pattern. IOCCSZ fix
enables inline write data (100K IOPS vs 15K before). R2T deadlock
fix via completeWaiters. Shutdown cleans up pendingCapsules buffers.
Bench: ParseFioMetric accepts plain/quoted numbers for aggregated
medians. Profiling actions: pprof_capture, vmstat_capture, iostat_capture.
196 NVMe tests, 92 testrunner actions.

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.
