Better fix for TOC showing previous article headings. The issue was
relying on pathname which could be out of sync with the actual content.
Changes:
- Pass contentKey as prop to PostToc instead of using usePathname()
- Use contentKey in useEffect dependency for more reliable updates
- Replace setTimeout with double requestAnimationFrame for DOM sync
- Remove unused usePathname import
This ensures the TOC effect runs exactly when the content changes,
not just when the URL changes, providing more reliable synchronization
between the TOC and the article content.
