[Feature]: Add Side-by-Side Code Comparison View for Version Analysis

Problem statement

Currently, users can analyze code individually, but there is no way to compare two versions of code within the platform. Developers often need to identify added, removed, or modified lines when reviewing changes, debugging, or learning from code revisions.

Proposed solution

Implement a split-screen comparison interface with two code editors:

1. Left panel: Original code
2. Right panel: Modified code
3. Highlight differences between versions
4. Display a summary of:

• Lines Added
• Lines Removed
• Lines Modified

Alternative solutions considered

• Using a single code editor with inline change highlights instead of a side-by-side view.
• Providing only a summary of added, removed, and modified lines without visual comparison.
• Integrating third-party diff tools for code comparison.
• Implementing a full version history and code snapshot management system.
• Allowing users to manually compare code versions without automated difference detection.

Use case or motivation

Developers often need to compare different versions of code to understand changes, review updates, and identify modifications efficiently. Currently, users can analyze code individually but lack a built-in way to compare two code snippets side by side. Adding a code comparison feature would improve the user experience by making code reviews, debugging, and learning from revisions more intuitive and time-efficient. It also enhances the platform's usefulness for collaborative and iterative development workflows.
