quoije 1a4330f291 Open menu naturally via chapter events; M returns to menu; debounce M

The menu state machine advances from the menu-intro state to the menu state
only when the menu video crosses its chapter-2 marker (onChapter). Fire
onChapter from the video loop as PTS crosses playlist markers. Also route the
M key through the onMenu dispatcher so it returns to the menu video/title
(not just drawing menu items), and debounce the key against auto-repeat.

Build

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

./gradlew build
