Wrap debug functionality in !HAKMEM_BUILD_RELEASE guard with no-op stubs for release builds. This eliminates getenv() calls for HAKMEM_TINY_ALLOC_DEBUG in production while maintaining API compatibility. Performance: 30.0M ops/s (baseline: 30.2M) 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
