feat!: migrate from ansis to util.styleText

[Copilot]

Removes the ansis external dependency by migrating to Node.js native util.styleText for terminal text styling.

Changes

• Created shared color utility (src/utils/color.utils.ts) wrapping util.styleText with helper functions
• Updated all command files to import from shared utility instead of ansis
• Removed ansis dependency from package.json
• Bumped minimum Node.js version to >=22.13.0 (where util.styleText is stable/backported)
• Added ESLint override for n/no-unsupported-features/node-builtins to allow util.styleText

Example

Before:

import { cyan, green, red, yellow } from 'ansis'

After:

import { cyan, green, red, yellow } from '../utils/color.utils.js'

Where color.utils.ts provides:

import { styleText } from 'node:util'

export const cyan = (text: string) => styleText('cyan', text)
export const green = (text: string) => styleText('green', text)
// ... etc

Original prompt

Prepare a PR to migrate the usages of ansis to the new util.styleText node utility (https://nodejs.org/docs/latest-v22.x/api/util.html#utilstyletextformat-text-options) to remove that external dependency.

Check compatibility after migration and update relevant package details if needed (e.g. increase min Node version identifier in package.json, etc..)
