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 Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
