Add “Release Type” Filter

📋 Summary

Add a new Release Type filter to LaunchBox’s filter options, allowing users to easily narrow their libraries or playlists by release classification — such as Official Release, Prototype, Homebrew, Unlicensed, or Beta.

🎯 Feature Overview

• Introduce a Release Type filter under the Quick Filter menu

• Allow multi-select functionality (e.g., view Released and Homebrew together).

• Fully integrated into both LaunchBox and Big Box views.

• Compatible with sorting, saved filters, and playlist creation.

🛠 Example Use Case

• A collector wants to browse only Prototypes and Betas to explore unreleased or early versions of games.

• A preservationist wants to exclude Unlicensed or Homebrew titles when viewing official collections.

📦 Benefits

• Makes it easier to curate and browse large, mixed libraries.

• Improves visibility of rare or unreleased titles for collectors and historians.

• Provides parity with metadata fields already available in the LaunchBox Games Database.

💡 Notes

The Release Type field already exists in the metadata model, so this feature would primarily require exposing it in the filter system and adding UI support for it.
