Source

// Refreshes src/lib/catalog.json, the copy of the OpenApps store's catalog that Subs ships with, so
// free alternatives show even before the live list loads (or when it cannot).
// Usage: npm run catalog [-- <catalog.json file or URL>]
// With no argument it asks the store's MCP server (list_free_apps), the same source the app reads live.
