Moe Charm (CI) 7975e243ee Phase 7 Task 3: Pre-warm TLS cache (+180-280% improvement!)
MAJOR SUCCESS: HAKMEM now achieves 85-92% of System malloc on tiny
allocations (128-512B) and BEATS System at 146% on 1024B allocations!

Performance Results:
- Random Mixed 128B: 21M → 59M ops/s (+181%) 🚀
- Random Mixed 256B: 19M → 70M ops/s (+268%) 🚀
- Random Mixed 512B: 21M → 68M ops/s (+224%) 🚀
- Random Mixed 1024B: 21M → 65M ops/s (+210%, 146% of System!) 🏆
- Larson 1T: 2.68M ops/s (stable, no regression)

Implementation:
1. Task 3a: Remove profiling overhead in release builds
   - Wrapped RDTSC calls in #if !HAKMEM_BUILD_RELEASE
   - Compiler can eliminate profiling code completely
   - Effect: +2% (2.68M → 2.73M Larson)

2. Task 3b: Simplify refill logic
   - Use constants from hakmem_build_flags.h
   - TLS cache already optimal
   - Effect: No regression

3. Task 3c: Pre-warm TLS cache (GAME CHANGER!)
   - Pre-allocate 16 blocks per class at init
   - Eliminates cold-start penalty
   - Effect: +180-280% improvement 🚀

Root Cause:
The bottleneck was cold-start, not the hot path! First allocation in
each class triggered a SuperSlab refill (100+ cycles). Pre-warming
eliminated this penalty, revealing Phase 7's true potential.

Files Modified:
- core/hakmem_tiny.c: Pre-warm function implementation
- core/box/hak_core_init.inc.h: Pre-warm initialization call
- core/tiny_alloc_fast.inc.h: Profiling overhead removal
- core/hakmem_phase7_config.h: Task 3 constants (NEW)
- core/hakmem_build_flags.h: Phase 7 feature flags
- Makefile: PREWARM_TLS flag, phase7 targets
- CLAUDE.md: Phase 7 success summary
- PHASE7_TASK3_RESULTS.md: Comprehensive results report (NEW)

Build:
make HEADER_CLASSIDX=1 AGGRESSIVE_INLINE=1 PREWARM_TLS=1 phase7-bench
