Phase v7-4: Policy Box 導入 (L3 層の明確化とフロント芯の作り直し)

Browse Source 
- SmallPolicyV7 Box: L3 Policy layer に配置、route 決定を一元化
- Route kind enum: SMALL_ROUTE_ULTRA / V7 / MID_V3 / LEGACY
- ENV priority (fixed): ULTRA > v7 > MID_v3 > LEGACY
- Frontend integration: v7 routing を Policy Box 経由に変更 (段階移行)
- Legacy compatibility: 既存の tiny_route_env_box.h は併用維持

Box Theory layer structure:
- L0: ULTRA (C4-C7, FROZEN)
- L1: SmallObject v7 (research box)
- L1': MID_v3 / LEGACY (fallback)
- L2: Segment / RegionId
- L3: Policy / Stats / Learner ← Policy Box added here

Frontend now follows clean "size→class→route_kind→switch" pattern.
ENV variables read once at Policy init, not scattered across frontend.

Future: ULTRA/MID_v3/LEGACY consolidation, Learner integration, flexible priority.
