e486dd2c55 Phase v4-mid-6: Implement C6 v4 TLS Fastlist (Gated) 
- Implemented TLS fastlist logic for C6 in smallobject_hotbox_v4.c (alloc/free).
- Added SmallC6FastState struct and g_small_c6_fast TLS variable.
- Gated the fastlist logic with HAKMEM_SMALL_HEAP_V4_FASTLIST (default OFF) due to observed instability in mixed workloads.
- Fixed a memory leak in small_heap_free_fast_v4 fallback path by calling hak_pool_free.
- Updated CURRENT_TASK.md with phase report.

e3e4cab833 Cleanup: Unify type naming and Cold Iface architecture 
Refactoring:
- Type naming: Rename small_page_v4 → SmallPageMeta, small_class_heap_v4 → SmallClassHeap, small_heap_ctx_v4 → SmallHeapCtx
- Keep backward compatibility aliases for existing code
- SmallSegment struct unified, clean forward declarations
- Cold Iface: Remove vtable (SmallColdIfaceV4 struct) in favor of direct function calls
- Simplify refill_page/retire_page to direct calls, not callbacks
- smallobject_hotbox_v4.c: Update to call small_cold_v4_* functions directly

Documentation:
- Add docs/analysis/ENV_CLEANUP_CANDIDATES.md
- Categorize ENVs: KEEP (production), RESEARCH (opt-in), DELETE (obsolete)
- v2 code: Keep as research infrastructure (complete, safe, gated)
- v4 code: Research scaffold for future mid-level allocator

Build:
- ビルド成功（警告のみ）
- Backward compatible, all existing code still works

52c65da783 Phase v4-mid-0: Small-object v4 型・IF 足場（箱化モジュール化） 
- SmallHeapCtx/SmallPageMeta/SmallClassHeap typedef alias 追加
- SmallSegment struct (base/num_pages/owner_tid/magic) を smallsegment_v4_box.h に定義
- SmallColdIface_v4 direct function prototypes (refill/retire/remote_push/drain)
- smallobject_hotbox_v4.c の internal/public API 分離（small_segment_v4_internal）
- direct function stubs 実装（SmallColdIfaceV4 delegate 形式）
- ENV OFF デフォルト（ENABLED=0/CLASSES=0）で既存挙動 100% 不変
- ビルド成功・sanity 確認（mixed/C6-heavy、segv/assert なし）
- CURRENT_TASK.md に Phase v4-mid-0 記録
