 * `subscribeDownloads()` — wraps both `murasaki:downloadstarted` and

 * callback. Requires the `webview:download` capability; without it, no
 * download handler is installed natively and neither event ever fires.
 *
 * There is no reliable id correlating a `started` event with the
 * `completed` event that follows it — wry's download-completed handler only
 * reports url/path/success (see `capabilities.json`'s `webview-session-network`
 * limitations) — so concurrent same-URL downloads may be ambiguous to tell
 * apart from `completed` alone.
