Thanks! Will need to find time to check the changes, but Coverage seems to not go through

I am also getting The CJS build of Vite's Node API is deprecated. See https://vitejs.dev/guide/troubleshooting.html#vite-cjs-node-api-deprecated for more details.

There's nothing wrong with that, electron now supports ESIM and it will be easy to switch in the future

I fixed the coverage, but there are some differences:

1. Vitest takes into account not only files in the app/utils folder, but also the entire app folder. This can be easily fixed by setting coverage: { include: ["app/utils"] }
2. Vitest also counts files without tests as 0% coverage. I believe this is the correct behavior, but if you disagree with me, this can also be changed via configuration.
3. We will need to create separate tests for the defaultBreakIdeas.js anddefaultMicrobreakIdeas.js files.

Otherwise, coverage is very similar

Thanks! I don't really care about the coverage number, I usually only look on difference when having new commits so looks good!
