/**
* List available @expo/ui components and modifiers installed in a project.
*
* Usage:
* node list-components.js <project-path> [--docs]
*
* --docs Include a one-line JSDoc description per modifier.
* Omit (default) for a compact names-only list that consumes fewer tokens.

* Output goes to stdout. Redirect or capture it to inject into an agent prompt.
