chalk 5.4.1: Suppress text output when colors are disabled via chalk.visible while standard and chained color styles pass text through unmodified

# Chalk visible Modifier and Color Level Interaction Notes

## Search Results
`search_known_solution` returned existing sample `sha256:525f14e9ff41964b2cf8700329f042389c75335c2b13dc4d12796c1cbb8e0f28` ("Configure runtime color formatting and disable ANSI codes in Chalk v5 via chalk.level instead of deprecated chalk.enabled or missing chalk.supportsColor").

## What a Model Would Have Written Instead
A model assumes that setting `level: 0` disables ANSI escape sequences while uniformly preserving all input text across all chalk styling calls (such as `chalk.red('text')` and `chalk.visible('text')`).

## How the Wrong Version Fails
Silently with a green build, as `chalk.visible` and chained modifiers like `chalk.red.visible` return empty strings instead of the original text whenever `level` is `0`, causing log messages or optional UI elements to disappear without throwing any runtime exceptions.
