Suggested Implementation Order

1. Add queue item helper and math.randomseed; these are low-risk cleanup.
2. Fix L2 input routing while preserving the quit combo.
3. Implement persisted favorites.
4. Implement sleep timer after deciding whether elapsed action is stop playback or quit RipTide.
5. Fix the playing-index assignment race.

Acceptance Criteria

• Options no longer contains a non-functional sleep timer item.
• Favorites persist across restart.
• L2 toggles favorite without breaking the quit combo.
• Shuffle order is not deterministic across launches.
• Queue screen still navigates and renders correctly.
• Audio playback and VOD playback do not regress.
• No EmulationStation restart, RG reboot, ES kill, or RipTide process kill is required for deployment.
