Phase 7: header-aware TLS front caches and FG gating

- core/hakmem_tiny_fastcache.inc.h: make tiny_fast_pop/push read/write next at base+1 for C0–C6; clear C7 next on pop
- core/hakmem_tiny_hot_pop.inc.h: header-aware next reads for g_fast_head pops (classes 0–3)
- core/tiny_free_magazine.inc.h: header-aware chain linking for BG spill chain (base+1 for C0–C6)
- core/box/front_gate_classifier.c: registry fallback classifies headerless only for class 7; others as headered

Build OK; bench_fixed_size_hakmem still SIGBUS right after init. FREE_ROUTE trace shows invalid frees (ptr=0xa0, etc.). Next steps: instrument early frees and audit remaining header-aware writes in any front caches not yet patched.

Debug Counters Implementation - Clean History

Major Features:
- Debug counter infrastructure for Refill Stage tracking
- Free Pipeline counters (ss_local, ss_remote, tls_sll)
- Diagnostic counters for early return analysis
- Unified larson.sh benchmark runner with profiles
- Phase 6-3 regression analysis documentation

Bug Fixes:
- Fix SuperSlab disabled by default (HAKMEM_TINY_USE_SUPERSLAB)
- Fix profile variable naming consistency
- Add .gitignore patterns for large files

Performance:
- Phase 6-3: 4.79 M ops/s (has OOM risk)
- With SuperSlab: 3.13 M ops/s (+19% improvement)

This is a clean repository without large log files.
