Circular Reference Handling

[krishana7911]

Plan:

• Use a WeakSet to track processed objects during recursion.
• If an object appears again, replace it with a [Circular] placeholder.

Steps:

1. Modify flattenJson to:

• Add objects to the WeakSet before recursion.
• Skip or replace the object if it already exists in the set.

2. Update the jsonToMarkdown.js file.

Challenges:

• Ensuring proper detection for objects vs. arrays.
• Avoiding performance overhead from additional checks.
