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 🤖 Generated with Claude Code Co-Authored-By: Claude Haiku 4.5 <noreply@anthropic.com>
