Change function description comments to tsdoc style (#35185)

1. change function comments to the minimal [tsdoc](https://tsdoc.org/)
style. This has the benefit of making editors show the doc string in
tooltips when the function is hovered:

<img width="521" height="110" alt="image"
src="https://github.com/user-attachments/assets/b966f4f1-8239-433a-a456-5bd5c05d69ef"
/>

2. disable eslint `multiline-comment-style` as it conflicts with tsdoc.
