Subject: [PATCH] [Performance] Optimize unstyled utility

Add an early return to the `unstyled` function in `packages/cli-kit/src/public/node/output.ts` to skip ANSI stripping for strings that don't contain the ESC character (`\u001b`). This avoids expensive regex execution for plain strings, which is a common case in terminal layout and logging paths.
