What issue are you seeing?

In the middle of a session, a red error message appeared, and the execution stopped:

``› discovered a bug when running a command (e.g., /rerun gemini`): the command name and the user input appears additionally at the very top of the chat. That duplicated
entry disappears again when the message is finalized, but it is still visible while the streaming is performed. Your tasks is to identify and solve this issue.

• Updated Plan
└ Investigate how /rerun is rendered during streaming, then adjust LiveView message streaming so optimistic/placeholder entries don’t appear as a duplicate at the top.
□ Locate rerun command handling
□ Reproduce streaming duplication path
□ Implement rendering/stream fix
□ Run quality and precommit checks
