// Peril Dice GitHub Updater - External Updater Box
// ====================================================================
// This script goes in a separate updater box object that users rez temporarily.
// Downloads scripts directly from GitHub and installs them automatically
// in target Peril Dice games via llRemoteLoadScriptPin().
//
// USAGE:
// 1. User rezzes this updater box near their Peril Dice game
// 2. User touches their game -> "Check for Updates" -> "Install Update"
// 3. Game communicates with this updater box for automatic installation
// 4. User deletes updater box when finished
