TUI Error: Cannot read properties of undefined (reading 'models') when selecting model

[oyabuya]

I encountered an error when using the TUI while selecting a model. The application crashes after a keypress.

Steps to Reproduce >>>
Run the CLI tool (free-coding-models)
Open the TUI interface
Navigate and select a model
Press a key to launch the selected model
Error occurs

Expected Behavior >>>
The selected model should start normally without crashing.

Actual Behavior >>>
The application throws an error and stops.

Error Log >>>
[TUI Error] An error occurred while handling a keypress.

Environment >>>
OS: Pop!_OS (Linux)
Node.js: v22.22.0
Installation: global via npm (free-coding-models)
Interface: TUI

Additional Notes >>>
This issue occurred during model selection. It seems that the models property is undefined when startOpenCode is called.
