Bug Description: Node 24 Not Supported

Okay, here's the heart of the matter: When you're using coveo/headless or coveo/bueno and you run npm install, you might see a warning that Node 24 isn't supported. The error message looks something like this:

npm warn EBADENGINE Unsupported engine {
npm warn EBADENGINE   package: '@coveo/[email protected]',
npm warn EBADENGINE   required: { node: '^20.9.0 || ^22.11.0' },
npm warn EBADENGINE   current: { node: 'v24.3.0', npm: '11.4.2' }
npm warn EBADENGINE }
npm warn EBADENGINE Unsupported engine {
npm warn EBADENGINE   package: '@coveo/[email protected]',
npm warn EBADENGINE   required: { node: '^20.9.0 || ^22.11.0' },
npm warn EBADENGINE   current: { node: 'v24.3.0', npm: '11.4.2' }
npm warn EBADENGINE }

This warning tells us that the @coveo/bueno and @coveo/headless packages explicitly support Node versions ^20.9.0 or ^22.11.0, but you're running Node v24.3.0. It's like trying to fit a square peg in a round hole – the packages aren't designed to work with this specific Node version. Node.js version compatibility is a critical factor in software development, and these warnings are your system's way of saying,
