[Bug]: TUI freezes/becomes unresponsive after switching workspaces (OpenCode CLI)

[Johannbr]

Current Behavior

Issue where a running TUI session (specifically opencode CLI) becomes completely unresponsive after switching away from the active workspace and switching back.

The TUI interface is frozen on the last rendered frame. Input is not registered visually, and the session appears "broken." The only way to recover the terminal block is to send a generic kill signal (Ctrl+C), which dumps me back to the standard shell prompt.

Expected Behavior

The TUI should resume rendering and accept input immediately upon returning to the workspace, preserving the session state.

Steps To Reproduce

1. Open a new terminal block in Workspace A.
2. Run the opencode CLI tool.
3. Switch to Workspace B (or any other workspace).
4. Switch back to Workspace A.
5. Attempt to interact with the opencode interface (scroll, type, etc.).

Hum, I've found a workaround:

1. Add a tab in Workspace A (called A-1)
2. Add a tab (called A-2)
3. Run the opencode CLI tool in A-1
4. Switch to Workspace B
5. Switch back to Workspace A
6. => OpenCode TUI is freezed in tab A-1
7. Click on tab A-2
8. Click on tab A-1
9. => the TUI works well

Basically, if the TUI freezes, you just have to click on another tab in the same workspace, then go back to the TUI tab's.

Thanks for the issue report and the instructions. Will try to repro and see what's going on
