"""Universal Mod Manager – GUI entry point.
Requires: pip install customtkinter Pillow   (already in .venv)
Run with: .venv/bin/python sbmm_gui.py

When packaged as a single frozen executable the GUI spawns subprocesses of
itself with CLI flags (--enable, --disable, etc.).  argv is inspected here so
those invocations are routed to the CLI backend instead of opening a second
GUI window.

nxm:// links are also handled here: if a running GUI instance is found via
the IPC socket, the URL is forwarded and this process exits immediately.
Otherwise the GUI starts with the URL queued for download.
