Problem: PreviewWatchStarted/PreviewWatchStopped were redundant with the status() API, and the doc had a wrong author, stale INSTALLATION format, and "watch mode" language left over from the watch → toggle rename. Solution: Remove the events and their tests. Fix the doc author, rename INSTALLATION → SETUP to match sibling plugins, replace "watch mode" with "auto-compile" throughout, and drop the events from EVENTS.
