Build GUI Chatbox for GPULlama3.java Inference with embedded GPU resource monitoring

## Description:

We want to create a user-friendly chat-style GUI for running LLM inference via our Java engine (powered by TornadoVM), inspired by the layout shown in the attached screenshot.

## Desired Features

* Prompt Input
* A text box where users can enter prompts for the LLM

* Dropdown Selectors
* Engine: Choose between TornadoVM, JVM, etc.
* Model: Select the model file to use for inference between Llama, Mistral etc

* File Picker
* A "Browse" button to select .java files or model directories

* Run Button
* A button to trigger inference (e.g., using tornado-llama-opencv)

* Output Display
* A read-only area to show model responses and logs
* Optional: System Monitoring Panel
* Live GPU usage via nvtop or nvidia-smi
* Live CPU & memory stats via htop or Java system metrics

Preferably, integrated with the core code base with JavaFX, or external with QT or python QT.
