Moe Charm (CI) e2ca52d59d Phase v6-6: Inline hot path optimization for SmallObject Core v6

Optimize v6 alloc/free by eliminating redundant route checks and adding
inline hot path functions:

- smallobject_core_v6_box.h: Add inline hot path functions:
  - small_alloc_c6_hot_v6() / small_alloc_c5_hot_v6(): Direct TLS pop
  - small_free_c6_hot_v6() / small_free_c5_hot_v6(): Direct TLS push
  - No route check needed (caller already validated via switch case)

- smallobject_core_v6.c: Add cold path functions:
  - small_alloc_cold_v6(): Handle TLS refill from page
  - small_free_cold_v6(): Handle page freelist push (TLS full/cross-thread)

- malloc_tiny_fast.h: Update front gate to use inline hot path:
  - Alloc: hot path first, cold path fallback on TLS miss
  - Free: hot path first, cold path fallback on TLS full

Performance results:
- C5-heavy: v6 ON 42.2M ≈ baseline (parity restored)
- C6-heavy: v6 ON 34.5M ≈ baseline (parity restored)
- Mixed 16-1024B: ~26.5M (v3-only: ~28.1M, gap is routing overhead)
