Summary

When visibleReplies is set to message_tool, agent replies are correctly delivered to Telegram/Discord via message(action=send), but those replies disappear from the WebChat/Control UI transcript after the next user message arrives. Confirmed on Telegram DM and Discord (all channels); WhatsApp and WeChat likely affected.

Steps to reproduce

opencode-go/qwen3.6-plus1. Set messages.visibleReplies: message_tool and messages.groupChat.visibleReplies: message_tool in config
2. Send a message via Telegram DM or Discord
3. Agent replies appear in chat surface — correct
4. Open WebChat/Control UI for same session — agent reply is visible
5. Send another message
6. Previous agent reply disappears from WebChat transcript — only user messages remain

Expected behavior

Agent replies sent via message tool should be mirrored back into the session transcript and remain persistently visible in WebChat/Control UI, just like in automatic mode.

Actual behavior

Agent replies delivered correctly to Telegram/Discord (visible in the chat app), but in WebChat/Control UI transcript they vanish after the next user turn. Only the users inbound messages remain; assistant turn content is gone from the UI.
