Moe Charm (CI) b2e861db12 Phase 67a: Layout tax forensics foundation (SSOT + measurement box) ...

Changes:
- scripts/box/layout_tax_forensics_box.sh: New measurement harness
  * Baseline vs treatment 10-run throughput comparison
  * Automated perf stat collection (cycles, IPC, branches, misses, TLB)
  * Binary metadata (size, section info)
  * Output to results/layout_tax_forensics/

- docs/analysis/PHASE67A_LAYOUT_TAX_FORENSICS_SSOT.md: Diagnostic reference
  * Decision tree: GO/NEUTRAL/NO-GO classification
  * Symptom→root-cause mapping (IPC/branch-miss/dTLB/cache-miss)
  * Phase 64 case study analysis (IPC 2.05→1.98)
  * Operational guidelines for Phase 67b+ optimizations

- CURRENT_TASK.md: Phase 67a marked complete, operational

Outcome:
- Layout tax diagnosis now reproducible in single measurement pass
- Enables fast GO/NO-GO decision for future code removal/reordering attempts
- Foundation for M2 (55% target) structural exploration without regression risk
