Agent cursor speed: a slider from 1× to 5× with Instant at the far right. Instant no longer breaks: the command runs at once (as with the cursor off) and the pointer jumps to where it acted, with a click ripple. ui.agent_cursor speed takes 1–5 or "instant"; saved "slow" and "normal" read as 1×. Scenario covers 1×, 3× and Instant against the cursor-off result

Fixes #79
