quoije 9a1e048264 Decode on a single background thread; add intro skip key

PlaybackEngine now runs one daemon decode thread that routes packets into
bounded queues, while the video/audio presenter threads only consume and
pace. This removes the demuxer contention that caused stutter, bursts, and
the speed-up/catch-up behavior.

Press S (or media next) during playback to skip the current playlist and
advance the menu's intro chain quickly.

Build

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

./gradlew build
