Moe Charm (CI) 118c0e4857 Phase FREE-DISPATCHER-OPT-1: free dispatcher 統計計測 ...

**目的**: free dispatcher（29%）の内訳を細分化して計測。

**実装内容**:
- FreeDispatchStats 構造体追加（ENV: HAKMEM_FREE_DISPATCH_STATS, default 0）
- カウンタ: total_calls / domain (tiny/mid/large) / route (ultra/legacy/pool/v6) / env_checks / route_for_class_calls
- hak_free_at / tiny_route_for_class / tiny_route_snapshot_init にカウンタ埋め込み
- 挙動変更なし（計測のみ、ENV OFF 時は overhead ゼロ）

**計測結果**:

Mixed 16-1024B (1M iter, ws=400):
- total=8,081, route_calls=267,967, env_checks=9
- BENCH_FAST_FRONT により大半は早期リターン
- route_for_class は主に alloc 側で呼ばれる（267k calls vs 8k frees）
- ENV check は初期化時の 9回のみ（snapshot 効果）

C6-heavy (257-768B, 1M iter, ws=400):
- total=500,099, route_calls=1,034, env_checks=9
- fg_classify_domain に到達する free が多い
- route_for_class 呼び出しは極小（snapshot 効果）

**結論**:
- ENV check は既に十分最適化されている（初期化時のみ）
- route_for_class は alloc 側での呼び出しが主で、free 側は snapshot で O(1)
- 次フェーズ（OPT-2）では別のアプローチを検討

**ドキュメント追加**:
- docs/analysis/FREE_DISPATCHER_ANALYSIS.md（新規）
- CURRENT_TASK.md に Phase FREE-DISPATCHER-OPT-1 セクション追加
