Image links printed lowercased, breaking case-sensitive URLs

	const responseText = result.response?.toLowerCase() ?? "";
	const imageRegex = /(https?:\/\/.*\.(?:png|jpg|gif))/gi;
	const images = responseText.match(imageRegex);
	if (images) {
	console.log(orange("\nImage links:"));
	images.forEach((img) => console.log(orange(`- ${img}`)));

const responseText = result.response?.toLowerCase() ?? "";
const imageRegex = /(https?:\/\/.*\.(?:png|jpg|gif))/gi;
const images = responseText.match(imageRegex);
if (images) {
  console.log(orange("\nImage links:"));
  images.forEach((img) => console.log(orange(`- ${img}`)));
}

Problem

The regex is matched against result.response.toLowerCase(), so the printed links come from the lowercased copy. Any URL with case-sensitive parts is corrupted:

input:  https://cdn.Example.com/AbC123/Img.PNG
shown:  https://cdn.example.com/abc123/img.png

This breaks links to case-sensitive hosts or paths (S3 keys, IPFS gateways, signed URLs with case-sensitive tokens, etc.).

Secondary: the extension list misses common image types such as .jpeg, .webp, and .svg.

Suggested fix

Match against the original response, not the lowercased copy:

const responseText = result.response ?? "";
const imageRegex = /(https?:\/\/\S+\.(?:png|jpe?g|gif|webp|svg))/gi;
const images = responseText.match(imageRegex);
