### Before submitting

- [x] I searched existing issues and did not find a duplicate.
- [x] I included enough detail to reproduce or investigate the problem.

### Area

apps/desktop

### Steps to reproduce

1. Start a session with opencode.
2. Chat for a bit until:
]0;`insert your macos username here`: ready build
appears as the first option for agent mode (normally build vs plan). (I've been unsuccessful in finding an actual repro)
3. Try to send a new message with that mode.

I've been using Hy3 Free and 5.6 Luna, probably up-stream provider agnostic.

### Expected behavior

It should just show build and plan. This is probably something to do with parsing something wrong somewhere.

### Actual behavior

It instead shows a jarbled bit of text and errors whenever you try to use build mode.
`]0;heinrich: ready build`

### Impact

Blocks work completely

### Version or commit

_No response_

### Environment

macos,opencode,desktop

### Workaround

Restart the application over and over until it returns to normal.
