MCP demo: examples/demo/enclosure_mcp.py builds an electronics enclosure in the running app over MCP, one execute call per step of enclosure_steps.json (rounded box, shell, USB port cut, four screw bosses, then width 80 -> 100 mm rebuilt), ending on an orbit; record.sh and captions.py record it with ffmpeg and burn in captions

+## Demo: an enclosure built over MCP
+
+`examples/demo/enclosure_mcp.py` is a small MCP client. It drives a running app (`solvecraft
+--control PORT`) through `solvecraft-cli mcp --connect` and builds an electronics enclosure one
+`execute` call at a time (`enclosure_steps.json`): a rounded box, shelled open at the top, a
+USB port cut through a side wall, four screw bosses, and then a change of the `width`
+parameter that the timeline rebuilds. `examples/demo/record.sh` records the run with ffmpeg,
+with each step's caption burnt in.
