Add Discord Rich Presence to LaunchBox for Android

📋 Summary

Add optional Discord Rich Presence support so users can display the game they are playing through LaunchBox for Android on their Discord profile.

❗ Problem

Discord activity support varies between Android emulators. Users cannot consistently share which game they are playing, particularly when their emulator has no built-in Discord integration.

💡 Proposal

Add an opt-in Discord Rich Presence setting.

When a game is launched through LaunchBox, the activity should display:

• Game title

• Platform

• Game artwork where available, with a generic fallback

Keep the activity visible while the game is being played, update it when another game is launched, and clear it when the session ends or sharing is disabled.

A LaunchBox Games Database match should help provide artwork, but should not be required to display the game title.

🧩 Use Cases

• Share what is being played on an Android handheld

• Display the game title when an emulator only identifies itself

• Provide activity sharing for emulators without native Discord support

📦 Benefits

• Provides a consistent sharing experience across supported emulators

• Makes friends’ current gaming activity easier to identify

• Reduces dependence on individual emulator integrations

⚠️ Considerations

• Sharing should be disabled by default and easy to turn off

• Session handling must account for returning to LaunchBox, device
