Shutdown quarto preview server more gracefully.

Description

When I use quarto preview to start a web server to preview the document I am writing, I have to shut it down by pressing Ctrl+c. This results in the following messages being printed to the terminal:

KeyboardInterrupt

I think Quarto could probably hide these warnings.

@it22318466 thanks, but taking the time to properly format your pasted LLM output would be appreciated before posting it.

Also do note that providing unverified LLM output is against the Code of Conduct, so before to fully proofread the content you decide to post from your LLM.

As clearly you did not review the content you posted or even Quarto CLI codebase, I'm hiding it.

While I understand the dislike of LLM generated content, I feel it's probably more productive to address the underline issue. This one really should be 2 minutes LLM coding fixable.

While I understand the dislike of LLM generated content, I feel it's probably more productive to address the underline issue.

The concern here is not with LLM-generated content as such, but with pasting content that is incorrect and was not verified before submission.

This one really should be 2 minutes LLM coding fixable.

Comments like this are not particularly productive or helpful to the team.
Quarto is maintained by a small team managing nearly two thousand open issues, and the focus right now is on Quarto 2 (in addition to Quarto 1), which addresses a much broader set of problems and unlocks features that cannot be delivered incrementally.
LLMs are not a reliable shortcut for ensuring a fix is correct, complete, and consistent across platforms.
If this feels straightforward to you, a pull request would be very welcome, including tests and cross-platform verification.
The contributions that move things forward most are those that come with a solution, not just a request.
Thanks for your continued interest in the project.

That is a fair point. I will try to fix this myself and test it on Linux and Windows.

But I do hope the team will have time for reviewing the (possibly very simple) pull request.
