Main Entry Point for AI Assistant Application

This script initializes and runs the AI Assistant application using PyQt5. 
It creates an instance of the `AssistantWindow` class and starts the application's event loop.

Modules:
    - sys: Provides access to system-specific parameters and functions, such as command-line arguments.
    - PyQt5.QtWidgets: Used for creating the application and managing the main event loop.
    - ui.main_window: Contains the `AssistantWindow` class that defines the main GUI for the assistant.

Usage:
    Run this script directly to start the AI Assistant application.
    Example: `python app.py`
