Ping QiuandClaude Opus 4.6 7940e6b7c9 feat: Phase 4A CP4b-4 Windows iSCSI + instrumentation + QA tests ...

Windows iSCSI Initiator compatibility:
- Add TargetPortalGroupTag to login response (RFC 7143 S13.9)
- Add REQUEST_SENSE, START_STOP_UNIT, MODE_SELECT(6/10) handlers
- Add PERSISTENT_RESERVE_IN/OUT, MAINTENANCE_IN (REPORT SUPPORTED OPCODES)
- Implement MODE SENSE caching (page 0x08) and control (page 0x0A) pages
- Fix Data-In residual underflow/overflow flags (U/O bits on final PDU)
- Rename ScsiReadCapacity16 -> ScsiServiceActionIn16 for correctness

Instrumentation and tooling:
- Add instrumentedAdapter with periodic PERF stats logging
- Add pprof endpoints on admin HTTP server (/debug/pprof/*)
- Add blockbench CLI tool for standalone block device benchmarking
- Add SCSI CDB debug logging in session dispatch

HA integration fixes:
- Move HA test replica ports to 9011-9014 to avoid conflicts
- Add QA adversarial tests for Phase 4A CP4b-4 (755 lines)
