Terminal tool progress on markdown-capable gateways (Telegram, Slack, Discord, WhatsApp, Matrix, Weixin, Feishu) renders the full command in a fenced code block again, in all/new AND verbose modes — gated on the adapter's supports_code_blocks capability. Plain-text platforms keep the short truncated preview. No language tag is emitted: Slack mrkdwn renders a '```bash' fence with 'bash' as a literal first code line, so a bare '```' fence is used, which renders correctly on every platform that supports blocks. This restores the #41215 feature (removed in #41950 due to the command showing in group chats) as the default. For a personal assistant the command display is desired; the group-chat concern is a preference, not a vulnerability.
