feat: use Playwright for caption, yt-dlp for thumbnail only

Always extract the full caption via Playwright (browser sees the
untruncated text). yt-dlp runs in parallel only to get the thumbnail
CDN URL quickly; its result for the description is discarded.

This eliminates the truncation problem at the source without needing
a fallback heuristic.
