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.

feat: Phase 9A -- Kubernetes operator MVP for SeaweedFS block storage, 71 tests
Nested Go module (operator/go.mod) isolating controller-runtime deps.
CRD SeaweedBlockCluster (block.seaweedfs.com/v1alpha1) with dual-mode:
CSI-only (MasterRef) connects to existing cluster; full-stack (Master)
deploys master+volume StatefulSets. Single reconciler manages all
sub-resources with ownership labels, finalizer cleanup, CHAP secret
auto-generation, and multi-CR conflict detection.
Review fixes: cross-NS label ownership (H1), ParseQuantity validation (H2),
volume readiness probe (M1), leader election (M2), PVC StorageClassName (M3),
condition type separation (M4), FQDN master address (L1), port validation (L3).
QA adversarial fixes: ExtraArgs override rejection (BUG-QA-1), malformed
lastRotated infinite rotation (BUG-QA-2), DNS label length validation
(BUG-QA-3), replicas=0 error message (BUG-QA-4), RFC 1123 name validation
(BUG-QA-5), whitespace field trimming (BUG-QA-6), zero storage size (BUG-QA-7).
