Relinking after the rebuild failed: the phone said "network error" and
signal-cli logged "Link request error: Connection closed!", with the network
itself fine (TLS to chat.signal.org completed). The pinned 0.100 bundled
signal-cli 0.14.5 from June; Signal stops accepting clients that fall a few
months behind. 0.101 (signal-cli 0.14.8) linked first time.
A stale pin fails the same way for alerts - silently - so the pin now carries
signal_api_version beside the digest and a note to bump it every couple of
months. The old comment saying upstream publishes no versioned tags was wrong.
