Web Content Fetcher

Given a URL, return its main content as clean Markdown — headings, links, images, lists, code blocks all preserved.

Note: This skill extracts content + remote image URLs. If the user wants an "offline" copy (download images to local disk and rewrite links), add a post-processing step (not included by default in this skill).

Extraction Strategy

Always try one method per URL — don't cascade blindly. Pick the right one upfront.
