Implement Phase 2: Next.js + React Flow frontend MVP
- Scaffold Next.js 15 app with TypeScript, Tailwind, App Router - Install @xyflow/react, Zustand, Lucide icons, nanoid - Define council types (AgentNodeData, CouncilBlueprint, WSMessage, etc.) - Implement Zustand store for canvas and run state - Build custom AgentNode component (label, system prompt, model badge, tool chips, active pulse) - Build ConditionalEdge component (dashed indigo line with condition label) - Build NodeSidebar (drag-and-drop + click to add agents) - Build NodeSettingsPanel (name, system prompt, model selector, tool toggles) - Build ArchitectCanvas (React Flow canvas with drop zone, minimap, controls) - Build blueprint parser (React Flow JSON ↔ CouncilBlueprint JSON) - Build API client for FastAPI backend (CRUD + run endpoints) - Build useCouncilWebSocket hook for live agent status via WebSocket - Build Tab A: Rat-Architekt (canvas builder with save/export toolbar) - Build Tab B: Konferenzzimmer (execution view with live diagram + result panel) - Add NavTabs navigation with CouncilOS branding - All TypeScript checks passing https://claude.ai/code/session_01EkbecUVn7esdxLCXxVVRDX
