feat: Distinguish between Local, Instance, and Static Variables with Examples and Comparison Table [var-scope-vip]

📌 Key Focus:
Provides a comprehensive explanation of local, global (instance), and static variables in Java with real-world examples, scope clarification, and a full comparison table.

🧠 Core Concepts:
- **Local Variable**: Declared within a method or block, short-lived, and not accessible outside.
- **Instance Variable (Global)**: Declared inside the class but outside methods, persists as long as the object exists.
- **Static Variable**: Declared with `static`, belongs to the class and shared among all objects, exists for the program lifetime.

📊 Includes:
- Scope, lifetime, and access control for each variable type
- Behavior of default values and initialization
- Real Java code demonstrating each type in action
- Output simulation and side-by-side table for easy comparison

💡 Educational Utility:
Perfect for learners or interview prep – emphasizes **when** and **why** to use each variable type in class design or memory management.
