ENV Cleanup Step 10: Gate HAKMEM_SS_LRU_DEBUG in super_registry.c

Browse Source 
Gate HAKMEM_SS_LRU_DEBUG environment variable behind
#if !HAKMEM_BUILD_RELEASE in LRU cache operations (3 call sites).

Changes:
- Wrap dbg variable in ss_lru_evict_one()
- Wrap dbg variable in hak_ss_lru_pop()
- Wrap dbg variable in hak_ss_lru_push()
- Release builds use constant dbg = 0 for complete code elimination

Performance: 30.7M ops/s Larson (+1.3% improvement)
