Proposal: Add --hide-captured-output to prek run

[pygarap]

Summary

As a follow-up to the discussion in #2578, add an opt-in --hide-captured-output flag to prek run.

When enabled, Captured Hook Output should be suppressed for every displayed hook result, including failed hooks whose output would normally be shown and hooks whose output is shown because of the global verbosity level or the hook's verbose setting.

The flag should only suppress Captured Hook Output and should not otherwise change metadata, execution, reporting, logging, or verbosity behavior.

Motivation

Verbose output provides useful hook metadata and duration, but Captured Hook Output can be too long and noisy.
--hide-status cannot address this because it hides the entire hook result.

Usage

$ prek run --all-files --verbose --hide-captured-output

The hook result should include its normal status and metadata without printing the Captured Hook Output.

Thanks, but I’m reluctant to add another flag for a narrow use case. I’d like to keep the CLI simple, and I don’t think the benefit here justifies the added complexity.
