/**
 * Plugin identity and update-check helpers. The Host reads the installed
 * package.json and queries the npm registry for the latest released version.
 * The browser never talks to the npm registry directly — the Host owns the
 * check and merely reports back a status plus the command the user runs to
 * update (DSH has no programmatic self-update API).
 *
 * Pattern follows the official `dsh-ears` plugin.
