Add AI Edit Undo/Revert Functionality

[Achuan-2]

I would like to request a feature that allows users to easily revert or undo AI-generated code changes after they have been applied.

Currently, once AI edits are implemented in Kilo Code, there's no convenient way to roll back those changes if the user is not satisfied with the results.

Expected Behavior:

• Add a prominent "❌" (cancel/revert) button next to AI-generated code suggestions or applied changes
• Allow users to quickly undo the last AI edit with a single click
• Provide a visual indication of what changes will be reverted before confirmation
• Optionally, maintain a history of AI edits for multi-step undo functionality

Inspiration:
GitHub Copilot provides an excellent user experience with its ability to easily revert AI suggestions. A similar implementation in Kilo Code would greatly enhance the user experience and provide more confidence when experimenting with AI-generated code.

Benefits:

• Increased user confidence in trying AI suggestions
• Reduced friction when AI output doesn't meet expectations
• Better user control over the code editing process
• Enhanced overall user experience

Hi @Achuan-2.

We have checkpoints for this. They should be enabled by default but if you don't see them, can you check in your settings if they are enabled? If so, you should see these checkpoints where you can view the diff with the first button and revert changes with the second one.

Let us know if this helps you please!
