quoije 43cc8f420c Fire onChapter on chapter boundaries; M returns to menu via onMenu

The menu state machine advances via onChapter events when a video crosses a
chapter marker, which we never emitted - so the menu never opened naturally.
Track chapter boundaries from the playlist markers and fire onChapter. Also
change M to invoke the onMenu dispatcher (returns to the menu video) rather
than drawing menu items directly.

Build

Requires JDK 21 (Gradle auto-provisions it via the Foojay toolchain resolver).

./gradlew build
