[Performance] Optimize unstyled utility

[gonzaloriestra]

WHY are these changes introduced?

The unstyled utility is used frequently in CLI operations, especially during logging and terminal layout calculations. The underlying stripAnsi function uses a complex regular expression that can be computationally expensive when called repeatedly on plain strings.

WHAT is this pull request doing?

Optimizes the unstyled function in packages/cli-kit/src/public/node/output.ts by adding an early return: if (!message.includes('\u001b')) return message. This avoids the regex overhead for any string that doesn't contain ANSI escape codes.

I'm pretty sure that we don't use this in a way that would have a meaningful performance impact, but ok

[gonzaloriestra]

Right, the improvement will be minimal. It will probably save a few ms only for outputs in non-TTY (no color). But the change is very simple.
