Add Tiny Free Gatekeeper Box for unified free entry point
Core Changes:
- New file: core/box/tiny_free_gate_box.h
* Thin wrapper around hak_tiny_free_fast_v2() with diagnostic hooks
* TinyFreeGateContext structure for USER→BASE + Bridge + Guard information
* tiny_free_gate_classify() - Detects header/meta class mismatches
* tiny_free_gate_try_fast() - Main gatekeeper function
* Zero performance impact when diagnostics disabled
* Future-ready for Guard injection
- Modified: core/box/hak_free_api.inc.h
* Added #include "tiny_free_gate_box.h" (line 12)
* Integrated gatekeeper into bench fast path (lines 113-120)
* Integrated gatekeeper into main DOMAIN_TINY path (lines 145-152)
* Proper #if HAKMEM_TINY_HEADER_CLASSIDX guards maintained
Design Rationale:
- Consolidates free path entry point: USER→BASE conversion and Bridge
classification happen at a single location
- Allows diagnostic hooks without affecting hot path performance
- Maintains backward compatibility: existing behavior unchanged when
diagnostics disabled
- Box Theory compliant: Clear separation of concerns, single responsibility
Testing:
- All smoke tests pass (test_simple_alloc, test_malloc_free_loop, test_pool_tls)
- No regressions in existing functionality
- Verified via Task agent (PASS verdict)
