/**
 * Open the OS share sheet, returning whether it actually opened.
 *
 * Two paths, because the Web Share API is not one API everywhere: Android's System WebView — which is
 * what the Capacitor app runs in — does not implement `navigator.share` at all, and even a WebView that
 * did would hide it in dev, where the app loads the cleartext `http://10.0.2.2:3000` (the Web Share API
 * is secure-context only). So native goes through the Capacitor bridge and the browser keeps using
 * `navigator.share`.
 *
 * `false` means "no sheet appeared" — the caller should fall back (copy the link, open a new tab, ...).
 * A user dismissing the sheet rejects the underlying promise too, so it also reports `false`; re-copying
 * the link after a deliberate cancel is harmless, and there is no way to tell the two apart.
