Phase: Pool API Modularization - Steps 1-2
Extract configuration, statistics, and caching boxes from pool_api.inc.h
Step 1: pool_config_box.h (60 lines)
- All ENV gate predicates (hak_pool_v2_enabled, hak_pool_v1_flatten_enabled, etc)
- Lazy static int cache pattern (matches tiny_heap_env_box.h style)
- Zero dependencies (lowest-level box)
Step 2a: pool_stats_box.h (90 lines)
- PoolV1FlattenStats structure with multi-phase support
- pool_v1_flat_stats_dump() with phase-aware output
- Destructor hook for automatic dumping on exit
- Multi-phase design: supports future phases without refactoring
Step 2b: pool_mid_desc_cache_box.h (60 lines)
- MidDescCache structure (TLS-local single-entry LRU)
- mid_desc_lookup_cached() with fast TLS hit path
- Minimal external dependency: mid_desc_lookup from pool_mid_desc.inc.h
Result: pool_api.inc.h reduced from 1050+ lines to ~950 lines
Still contains: alloc/free implementations, helpers (next steps)
Build: ✅ Clean (no warnings)
Test: ✅ Benchmark passes (8.5M ops/s)
