[suggestion] improved watch stop

[MarcoBuess]

@Zeioth I wonder if it would make sense, instead of tracking the last execution over a grace period to rather capture the buffer that is currently served and monitor the last write time. Then go and reset the grace period when the buffer was recently written, as one could assume that you are still working on the document. I haven't looked up what the default grace period is but serving just randomly stopped after ~1h when I was still editing the document.

This would also allow for an autocommand that would stop markmap-cli when the served buffer is closed.
Edit: Which, now that I think about it, could eliminate the need for a grace period alltogehter. Just leave it serving while the buffer is open and shut it down when it closes or nvim exits.

This is the expected behavior, and the simple solution is to just increase the default grace_period from 1h to what you need.

But if you see it's not gonna increase complexity too much and want to send a PR go for it. It is a cool feature.

I just wanted to check, if it's cool with you. I'll see what I can do in terms of a PR. 🚀
