**Problem**: Include order dependency prevented using TINY_FRONT_FASTCACHE_ENABLED
macro in hakmem_tiny_refill.inc.h (included before tiny_alloc_fast.inc.h).
**Solution** (from ChatGPT advice):
- Move wrapper functions to tiny_front_config_box.h as static inline
- This makes them available regardless of include order
- Enables dead code elimination in PGO mode for refill path
**Changes**:
1. core/box/tiny_front_config_box.h:
- Add tiny_fastcache_enabled() and sfc_cascade_enabled() as static inline
- These access static global variables via extern declaration
2. core/hakmem_tiny_refill.inc.h:
- Include tiny_front_config_box.h
- Use TINY_FRONT_FASTCACHE_ENABLED macro (line 162)
- Enables dead code elimination in PGO mode
3. core/tiny_alloc_fast.inc.h:
- Remove duplicate wrapper function definitions
- Now uses functions from config box header
**Performance**: 79.8M ops/s (maintained, 77M/81M/81M across 3 runs)
**Design Principle**: Config Box as "single entry point" for Tiny Front policy
- All config checks go through TINY_FRONT_*_ENABLED macros
- Wrapper functions centralized in config box header
- Include order independent (static inline in header)
