Feature Request: Support Hackatime in Kaggle Notebooks

# Feature Request: Support Hackatime in Kaggle Notebooks

## Summary

I'd like Hackatime to support tracking coding time in Kaggle Notebooks.

## Problem

Many people learning machine learning and data science use Kaggle because it provides free GPUs, TPUs, and a cloud-based Jupyter environment. However, Hackatime currently doesn't work in Kaggle, so time spent coding and experimenting there isn't tracked.

## Proposed Solution

Add official support for Kaggle Notebooks, for example through:

* A Jupyter Notebook extension compatible with Kaggle.
* A lightweight Python package that can report coding activity from Kaggle.
* Any other method that allows Hackatime to track active coding time in Kaggle.

## Why this would be useful

* Many students and beginners rely on Kaggle's free compute resources.
* Machine learning workflows are often developed entirely in Kaggle notebooks.
* It would allow Hackatime users to accurately track time spent learning and building ML projects.
* This could encourage more data science and machine learning users to adopt Hackatime.

Thanks for considering this feature!

The issue names no files, tests, or entry points. First investigate how Kaggle Notebooks run Jupyter code and determine whether a notebook extension, Python package, or another approach can report active coding time. Done means Hackatime reliably tracks coding activity in Kaggle Notebooks.
