JSON Diff Checker

This tool performs a deep comparison of two JSON structures. It detects three types of changes:

• Added — keys present in the modified JSON but absent from the original.
• Removed — keys present in the original but absent from the modified version.
• Changed — keys present in both but with different values.

Keys that are identical in both documents are not reported — keeping the diff output focused on what matters. Nested objects are compared recursively with full key paths.
