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

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）

Tiny: Enable P0→FC direct path for class7 (1KB) by default + docs

- Class7 (1KB): P0 direct-to-FastCache now default ON (HAKMEM_TINY_P0_DIRECT_FC_C7 unset or not '0').
- Keep A/B gates: HAKMEM_TINY_P0_ENABLE, HAKMEM_TINY_P0_DIRECT_FC (class5), HAKMEM_TINY_P0_DIRECT_FC_C7 (class7),
  HAKMEM_TINY_P0_DRAIN_THRESH (default 32), HAKMEM_TINY_P0_NO_DRAIN, HAKMEM_TINY_P0_LOG.
- P0 batch now supports class7 direct fill in addition to class5: gather (drain thresholded → freelist pop → linear carve)
  without writing into objects, then bulk-push into FC, update meta/active counters once.
- Docs: Update direct-FC defaults (class5+class7 ON) in docs/TINY_P0_BATCH_REFILL.md.

Notes
- Use tools/bench_rs_from_files.sh for RS(hakmem/system) to compare runs across CPUs.
- Next: parameter sweep for class7 (FC cap/batch limit/drain threshold) and perf counters A/B.

Tiny: Enable P0 batch refill by default + docs and task update

Summary
- Default P0 ON: Build-time HAKMEM_TINY_P0_BATCH_REFILL=1 remains; runtime gate now defaults to ON
  (HAKMEM_TINY_P0_ENABLE unset or not '0'). Kill switch preserved via HAKMEM_TINY_P0_DISABLE=1.
- Fix critical bug: After freelist→SLL batch splice, increment TinySlabMeta::used by 'from_freelist'
  to mirror non-P0 behavior (prevents under-accounting and follow-on carve invariants from breaking).
- Add low-overhead A/B toggles for triage: HAKMEM_TINY_P0_NO_DRAIN (skip remote drain),
  HAKMEM_TINY_P0_LOG (emit [P0_COUNTER_OK/MISMATCH] based on total_active_blocks delta).
- Keep linear carve fail-fast guards across simple/general/TLS-bump paths.

Perf (1T, 100k×256B)
- P0 OFF: ~2.73M ops/s (stable)
- P0 ON (no drain): ~2.45M ops/s
- P0 ON (normal drain): ~2.76M ops/s (fastest)

Known
- Rare [P0_COUNTER_MISMATCH] warnings persist (non-fatal). Continue auditing active/used
  balance around batch freelist splice and remote drain splice.

Docs
- Add docs/TINY_P0_BATCH_REFILL.md (runtime switches, behavior, perf notes).
- Update CURRENT_TASK.md with Tiny P0 status (default ON) and next steps.
