fix: enable hash link scrolling in README Table of Contents

When clicking on hash links within a package's README (such as Table of
Contents links), the URL hash would update but the page wouldn't scroll
to the target section. This was because the click handler wasn't
processing internal anchor links.

The fix intercepts clicks on hash links (href starting with #) and uses
the existing scrollToAnchor utility to smoothly scroll to the target
section with proper header offset handling.

Fixes #1008
