dd974b49c5 Phase v4-mid-2, v4-mid-3, v4-mid-5: SmallObject HotBox v4 implementation and docs update 
Implementation:
- SmallObject HotBox v4 (core/smallobject_hotbox_v4.c) now fully implements C6-only allocations and frees, including current/partial management and freelist operations.
- Cold Iface (tiny_heap based) for page refill/retire is integrated.
- Stats instrumentation (v4-mid-5) added to small_heap_alloc_fast_v4 and small_heap_free_fast_v4, with a new header file core/box/smallobject_hotbox_v4_stats_box.h and atexit dump function.

Updates:
- CURRENT_TASK.md has been condensed and updated with summaries of Phase v4-mid-2 (C6-only v4), Phase v4-mid-3 (C5-only v4 pilot), and the stats implementation (v4-mid-5).
- docs/analysis/SMALLOBJECT_V4_BOX_DESIGN.md updated with A/B results and conclusions for C6-only and C5-only v4 implementations.
- The previous CURRENT_TASK.md content has been archived to CURRENT_TASK_ARCHIVE_20251210.md.
