fix: only replace URLs in href attributes, not in link text

The link rewriting was replacing ALL occurrences of the URL,
including visible link text. Now it only replaces within
href="..." or href='...' attributes.

Before: <a href="tracking-url">tracking-url</a>
After:  <a href="tracking-url">original-url</a>
