 * The lease command is the only way to reach the client's retained webview: the host protocol
 * carries no worktree, so a client cannot scope this itself. The runtime record is dropped whether
 * or not the client acknowledges — worktree IDs are path-derived and can be recreated, so a
 * surviving record would republish the dead worktree's tabs and let reconnect recovery
 * re-materialize a webview for a page nobody can reach any more.
