ENV Cleanup Step 11: Gate HAKMEM_SS_PREWARM_DEBUG in super_registry.c

Browse Source 
Gate HAKMEM_SS_PREWARM_DEBUG environment variable behind
#if !HAKMEM_BUILD_RELEASE in prewarm functions (2 call sites).

Changes:
- Wrap dbg variable in hak_ss_prewarm_class()
- Wrap dbg variable in hak_ss_prewarm_init()
- Release builds use constant dbg = 0 for complete code elimination

Performance: 30.2M ops/s Larson (stable, within expected variance)
