ENV cleanup: Remove BG/HotMag vars & guard fprintf (Larson 52.3M ops/s)

Browse Source 
Phase 1 完了：環境変数整理 + fprintf デバッグガード

ENV変数削除（BG/HotMag系）:
- core/hakmem_tiny_init.inc: HotMag ENV 削除 (~131 lines)
- core/hakmem_tiny_bg_spill.c: BG spill ENV 削除
- core/tiny_refill.h: BG remote 固定値化
- core/hakmem_tiny_slow.inc: BG refs 削除

fprintf Debug Guards (#if !HAKMEM_BUILD_RELEASE):
- core/hakmem_shared_pool.c: Lock stats (~18 fprintf)
- core/page_arena.c: Init/Shutdown/Stats (~27 fprintf)
- core/hakmem.c: SIGSEGV init message

ドキュメント整理:
- 328 markdown files 削除（旧レポート・重複docs）

性能確認:
- Larson: 52.35M ops/s (前回52.8M、安定動作✅)
- ENV整理による機能影響なし
- Debug出力は一部残存（次phase で対応）
