CLI flags for ignoring project scripts on render/preview

[pj398]

Description

I just ran into an issue (which is discussed by others in #12987 and Discussion #13052) when trying to preview a notebook. I have a post-render script that moves the output files to a different location within the project, and thus quarto preview failed with the "no output created by quarto render" error because it can't serve the output file from its expected location.

One thing that would solve this problem is adding flags like --no-pre-render-scripts/--no-post-render-scripts which allow either quarto render or quarto preview to ignore the scripts on request. Such a feature would be very valuable as it gives the user much greater flexibility on how and when to incorporate project scripts into their workflow, though I couldn't see any existing feature request for this.

Use profiles. This feature is there exactly for these cases.

See Project profiles.

You can also better control your scripts using the variables provided by Quarto: https://quarto.org/docs/projects/scripts.html#pre-and-post-render
