Understand CPython's Reference Counting

Write a C program demonstrating reference counting.

Requirements:

• Define a simple object struct with refcnt and name fields
• Implement simulated Py_INCREF and Py_DECREF macros/functions
• Show object creation (refcnt=1), assignment ( incref), deletion (decref)
• Demonstrate when an object is freed (refcnt reaches 0)
• Show a reference cycle scenario and explain why it isn't freed immediately
• Print refcnt values at each stage
• Explain the limitation and mention cycle detection
