Add: Allocation path tracking for debugging

Browse Source 
Added HAK_RET_ALLOC_BLOCK_TRACED macro with path identifiers:
- ALLOC_PATH_BACKEND (1): SuperSlab backend allocation
- ALLOC_PATH_TLS_POP (2): TLS SLL pop
- ALLOC_PATH_CARVE (3): Linear carve
- ALLOC_PATH_FREELIST (4): Freelist pop
- ALLOC_PATH_HOTMAG (5): Hot magazine
- ALLOC_PATH_FASTCACHE (6): Fast cache
- ALLOC_PATH_BUMP (7): Bump allocator
- ALLOC_PATH_REFILL (8): Refill/adoption

Usage:
  HAKMEM_ALLOC_PATH_TRACE=1 ./larson_hakmem ...

Logs first 20 allocations with path ID for debugging.

Updated SuperSlab backend to use traced version.
