 * Defaults to `window.location.href`, but honors the `get_current_url` config hook so apps
 * that rewrite their URL (e.g. Electron/desktop builds, or `$current_url` rewrites in
 * `before_send`) can make targeting match the logical URL instead of the raw browser URL.
 *
 * Returns `undefined` when there is no URL available (e.g. non-browser environments).
 *
 * Called on every rrweb event by the replay URL triggers/blocklist, so a configured
 * `get_current_url` override should stay cheap.
