MCP demo v2: examples/demo/enclosure_ui_mcp.py builds the enclosure through the UI like a person (toolbar clicks, real dialogs, sketches on the model's faces, Look At and back out, orbits between features) with the parameters and their dimensions over MCP; record_v2.sh and overlay.py record it with captions (UI click / MCP call) and a drawn pointer with click ripples. Toolbar buttons, drop-down items and panel labels publish handles (toolbar:<id>, panel:<tab>:<panel>); control method ui.handles lists them
