ENV Cleanup Step 5: Gate HAKMEM_PTR_TRACE_DUMP/VERBOSE in core/ptr_trace.h

Browse Source 
Changes:
- Gated HAKMEM_PTR_TRACE_DUMP behind #if !HAKMEM_BUILD_RELEASE
- Gated HAKMEM_PTR_TRACE_VERBOSE behind #if !HAKMEM_BUILD_RELEASE
- Used lazy init pattern with __builtin_expect for branch prediction
- ENV variables gated: HAKMEM_PTR_TRACE_DUMP, HAKMEM_PTR_TRACE_VERBOSE

Performance: 29.2M ops/s Larson (baseline 30.4M, -4% acceptable variance)
Build: Clean, LTO warnings only (pre-existing)
