Moe Charm (CI) 17ceed619c Phase v7-5a: Hot path stats removal (C6 v7 極限最適化) ...

- Remove per-page stats from hot path (alloc_count, free_count, live_current)
- Add ENV-gated global atomic stats (HAKMEM_V7_HOT_STATS)
- Stats now collected only at retire time (cold path)
- Header write kept at alloc time (freelist overlaps block[0])

A/B Result: -4.3% overhead → ±0% (target: legacy ±2%)
v7 OFF avg: 9.26M ops/s, v7 ON avg: 9.27M ops/s (+0.15%)
