Describe the feature

Currently, there is no direct way to stop the generation.

A feature to stop the generation would be helpful in scenarios where long-running agents need to be stopped to re-submit the prompt if improvements or fixes are identified after submission.

Hi @ashish-spext, I've attempted this issue and raised a PR. Could you please review it and let me know if the changes are acceptable?
Also, should I start working on the frontend part to add a visible Stop button for users?
