Phase 2: Add notification system and improve dependency management
- Added notify_v2.sh wrapper for advanced notification management - Updated Discord and Gotify notification templates for v2 compatibility - Added snooze functionality to prevent duplicate notifications - Added support for multiple notification channels and formats (JSON, CSV, text) - Implemented robust dependency management system with package manager and static binary fallback - Added helper functions: releasenotes(), list_options(), progress_bar() - Improved datecheck() function with proper error handling - Added distro_checker() and binary_downloader() functions - Replaced old dependency checks with modern dependency_check() system
