feat: Simulate School Management System using instance vs global (static) variables [school-static-instance-demo]

🎯 Purpose:
Demonstrates the use of both instance and static variables to model real-world objects in a school setup.

📌 Key Features:
- 👤 **Instance Variables**: Each `Student` has a unique `name` and `rollNumber`.
- 🌐 **Static Variables**:
  - `schoolName`: Shared across all students.
  - `totalStudents`: Tracks the number of student instances created globally.
- 🧾 **Static Method**: `displayTotalStudents()` shows the total number of students enrolled.
