To-Do In-Memory Python Console App

This is a simple To-Do application implemented as a Python console application. It allows users to manage their tasks with basic CRUD (Create, Read, Update, Delete) operations, and also mark tasks as complete or incomplete. All data is stored in memory and will be lost when the application closes.

Features

• List Tasks: View all existing tasks with their ID, title, description, and completion status.
• Update Task: Modify the title or description of an existing task.
• Delete Task: Remove a task from the list.
• Toggle Task Status: Mark a task as complete or incomplete.
