The TOC was displaying sections from previously viewed articles when
navigating between posts. This happened because the DOM query for
headings ran before Next.js finished updating the page content.
Changes to components/post-toc.tsx:
- Clear items and activeId immediately when pathname changes
- Add 50ms delay before querying DOM for new headings
- Properly handle IntersectionObserver cleanup with timeout
This ensures the TOC always shows the correct headings for the
current article, not the previous one.
