Agent cursor: a violet pointer labelled Agent acts out control-channel and MCP commands. It glides to the command's toolbar button (or its panel) and clicks with a ripple, then to each pick (faces, edges and points projected to the screen, sketch points, a new sketch's plane, the profiles an extrude takes), then the command runs; the reply waits for it and later requests queue behind. Speed instant/normal/slow; follow camera turns to a new sketch and back on finish. View settings on the navigation bar (Show Agent Cursor, speed, follow camera; remembered, off by default); ui.agent_cursor {show, speed, follow_camera}; "animate": false per call. Tests: pick to screen mapping; scenario with the cursor on (replies wait for the animation) matching the cursor-off result

Fixes #35
