Phase v11a-3: MID v3.5 Activation (Build Complete)

Browse Source 
Integrated MID v3.5 into active code path, making it available for C5/C6/C7 routing.

Key Changes:
- Policy Box: Added SMALL_ROUTE_MID_V35 with ENV gates (HAKMEM_MID_V35_ENABLED, HAKMEM_MID_V35_CLASSES)
- HotBox: Implemented small_mid_v35_alloc/free with TLS-cached page allocation
- Front Gate: Wired MID_V35 routing into malloc_tiny_fast.h (priority: ULTRA > MID_V35 > V7)
- Build: Added core/smallobject_mid_v35.o to all object lists

Architecture:
- Slot sizes: C5=384B, C6=512B, C7=1024B
- Page size: 64KB (170/128/64 slots)
- Integration: ColdIface v2 (refill/retire), Stats v2 (observation), Learner v2 (dormant)

Status: Build successful, ready for A/B benchmarking
Next: Performance validation (C6-heavy, C5+C6-only, Mixed benchmarks)
