Initial commit: Claude Co-Engineer

A Factorio 2.x mod plus MCP server that lets Claude answer questions about
a running game over Lua UDP, without RCON, so it works in singleplayer.

- Read-only tools: overview, problems, entities, production, power, trends,
  research, recipes, ratio calculator, belt tracer, screenshots, Lua queries
- In-game highlights with clickable [gps] links
- /ask chat command answered by a local helper running claude -p, with a
  per-player model setting and a systemd user service
