# Description:
# Main entry point for ProxMenux.
# - Loads configuration and utility functions.
# - Detects if running in Beta Program mode (develop branch).
# - Checks for updates from the appropriate branch (main or develop).
# - In beta mode: compares beta_version.txt; notifies when a stable
#   release is available and prompts the user to switch.
# - Launches the main menu.
