ENV Cleanup Step 16: Gate HAKMEM_SS_FREE_DEBUG

Browse Source 
Gate the shared pool free debug variable behind #if !HAKMEM_BUILD_RELEASE:
- HAKMEM_SS_FREE_DEBUG: Controls shared pool slot release tracing
- File: core/hakmem_shared_pool.c:1221-1229

The debug output was already gated inside #if !HAKMEM_BUILD_RELEASE blocks.
This change only gates the ENV check itself. In release builds, sets
dbg to constant 0, allowing compiler to optimize away checks.

Performance: 30.3M ops/s (baseline maintained)
