feat(phase-6.4g-6.5b): API Synaptic Integration + Dual-State WarRoom UI

Phase 6.4g (API 突觸對接):
- lewooogo-brain dependency binding in apps/api/pyproject.toml
- POST /api/v1/incidents/{id}/propose route (proposals.py)
- Guardrails integration (8/8 tests passed)

Phase 6.5a (視覺皮層建置):
- DualStateIncidentCard.tsx with Nothing.tech visual compliance
- Ping radar animation for alert state
- Tier-based decision layer UI (AI 執行中 / 等待親核)

Phase 6.5b (神經網路串接):
- Main warroom page integration (page.tsx)
- IncidentResponse → DualState mapper function
- Empty state: "系統穩定。0 活躍異常。"

Tests:
- test_guardrails.py (8/8)
- test_incident_engine.py (6/6)
- test_skill_loader.py (6/6)
- Frontend build: 0 errors
