RG40XXV GameSurface Working Prototype

The game surface and the keyboard mission are separate layers.

• Game surface: a generic RG40XXV client for any 36-tile graph correspondence. It renders the board, units, nested graph/state menus, review flows, routing actions, and server state without knowing that a node is specifically about keyboard research.
• Current staged mission fixture: the keyboard/input research pass. Its 36 cells, criteria, phase names, prerequisites, and task qualia are configured on the Pi LangGraph server as node data. Rif, Echo, and Sherpa move through that fixture to validate that the generic surface can map onto and operate a real graph.
