// Package main provides the BugSETI system tray application.
// BugSETI - "Distributed Bug Fixing like SETI@home but for code"
//
// The application runs as a system tray app that:
// - Pulls OSS issues from Forgejo
// - Uses AI to prepare context for each issue
// - Presents issues to users for fixing
// - Automates PR submission
