Fixes GTK4 Layer Shell and Ollama integration issues

Addresses multiple issues related to GTK4 Layer Shell initialization and Ollama integration.

- Reorders initialization to ensure the layer shell is set up before window properties.
- Adds error detection for layer shell initialization failures.
- Implements a focus event handler to prevent focus-out warnings.
- Introduces a launcher script to activate the virtual environment, force native Wayland, and preload the GTK4 Layer Shell library.
- Warns users of incorrect GDK_BACKEND settings.
- Updates the Ollama client to handle responses from both older and newer versions of the Ollama SDK.

These changes improve the application's stability, compatibility, and functionality on Wayland systems.
