Scaffold project and author 14-phase roadmap

Browser co-op kitchen game: FastAPI + native WebSockets, server-authoritative
20 Hz simulation, in-memory anonymous lobbies, data-driven YAML levels, Canvas 2D
vanilla ES-module client with locally authored SVG art and no external CDNs.

.agents/PLAN.md records the LOCKED decisions; .agents/user_stories/ holds the 12
flow contracts; .agents/phases/todo/ breaks them into 14 sequential, test-gated
phases (71 task files), each leaving the app launchable and the suite green.
