Channels: default-only threading + automation (read-only) channels — threading (topic switcher, Ctrl+T, auto-threading) is now only active on the default channel, and the gateway ignores auto_thread for other channels; new channel.set_automation frame marks a channel read-only for cron/webhook output (app hides the composer behind a notice, gateway rejects message.send, default channel cannot be marked, flag syncs to all devices via the full-entry channel.renamed response, gear badge in the list); header pill drops the 'Bot' subtitle and shows the chat_id on automation channels (tap to copy for cron delivery targeting); also fixes a pre-existing stray brace that made frames.schema.json invalid JSON
