Moe Charm (CI) 0a7400d7d3 Phase ALLOC-TINY-FAST-DUALHOT-1: C0-C3 alloc direct path (WIP, -2% regression) ...

Add C0-C3 early-exit optimization to malloc_tiny_fast() similar to
FREE-TINY-FAST-DUALHOT-1. Skip policy snapshot for C0-C3 classes.

A/B Result (10-run, Mixed TINYV3_C7_SAFE):
- Baseline: 47.27M ops/s (median)
- Optimized: 46.10M ops/s (median)
- Result: -2.00% (regression, needs investigation)

ENV: HAKMEM_TINY_ALLOC_DUALHOT=0/1 (default OFF)

Implementation:
- core/front/malloc_tiny_fast.h: alloc_dualhot_enabled() + early-exit
- Design: docs/analysis/ALLOC_TINY_FAST_DUALHOT_1_DESIGN.md

Status: Research box (default OFF), needs root cause analysis
