Add Installed Status and Launch Shortcut to Big Box Leaderboards

📋 Summary

Show whether leaderboard games are installed in the user’s local library and allow installed games to be launched directly from the Big Box leaderboard screen.

❗ Problem

When browsing global high score leaderboards in Big Box, users may find a game they want to play immediately.

Currently, they need to leave the leaderboard screen, search for the game in their library, and launch it separately.

💡 Proposal

Add two improvements to Big Box leaderboards:

• A clear installed/available indicator for games already in the local LaunchBox library

• A direct Play Game action for installed games

This would let users move from viewing a leaderboard challenge to launching the game with minimal friction.

🧩 Use Cases

• See whether a leaderboard game is already available locally

• Launch an installed game directly from its leaderboard entry

• Quickly attempt to beat a high score after viewing rankings

• Browse leaderboards as a way to discover what to play next

📦 Benefits

• Smoother leaderboard-to-game flow

• Better use of leaderboards as a play discovery tool

• Fewer steps for competitive players

• More engaging Big Box experience

⚠️ Considerations

The launch action should only appear when LaunchBox can confidently match the leaderboard game to an installed local game.
