This pull request replaces the dependency on listr2 for terminal coloring in packages/angular/cli/src/utilities/color.ts with a custom implementation using Node's native styleText from node:util. However, using styleText directly introduces compatibility issues with older Node.js versions supported by Angular CLI and fails to respect color support detection in non-TTY environments. It is recommended to implement a fallback mechanism and wrap the formatting calls to conditionally apply colors based on terminal support.

Replaces listr2 re-exports in the CLI color helper with Node.js built-in `styleText` utilities from `node:util`. Previously, importing colors from `utilities/color.ts` eagerly pulled in `listr2` along with its transitive dependencies (`wrap-ansi`, `string-width`, `get-east-asian-width`), introducing synchronous ESM module evaluation and ANSI formatting overhead during early CLI startup.
