/**
 * External dependency detection and install for the CLI/platform backends.
 * Most backends shell out to tools installed outside DSH (bili, yt-dlp,
 * agent-reach, and mcporter). This module reports which are
 * present and how to install them; the web_deps tool exposes it to the model.
 *
 * Install is intentionally a MODEL-FACING TOOL, not a browser settings button:
 * a browser button running winget/pip/npm would be arbitrary command execution
 * without a permission gate, whereas a tool flows through DSH's existing
 * tool-permission/approval pipeline. The card points at this tool instead.
 * @module web-search-pro/deps
