// Commandes disponibles :
//   qrpanel init        → écrit .qrconfig.json à cwd avec les defaults
//   qrpanel themes      → liste les 12 thèmes natifs
//   qrpanel --version   → version du package

Usage:
  qrpanel init [path]      Generate .qrconfig.json at cwd (or [path]).
                           Idempotent — does not overwrite existing config.
  qrpanel themes           List built-in theme keys.
  qrpanel --version | -v   Print version.
  qrpanel help | -h        This help.

Config file (.qrconfig.json) drives all generators. Master toggle:
  "genimage": false  → bypass theme pipeline, QR-only output.
  "theme": "random"  → randomize from themePool at each generation.
