// There is exactly one embedded Tor client shared by the whole daemon (see
// chatd-rs's net/tor.rs TorManager) - not one per account - so everything
// here is daemon-global: which transport mode Sneedchat accounts use, and
// actions on the shared circuit/client itself. Contrast with
// SneedchatSettingsPanel.qml's "Channels" section, which is genuinely
// per-account.
