fix(reddit,bilibili): switch to rdt-cli and add bili-cli support (#235)

Reddit: Exa crawling had chronic CRAWL_LIVECRAWL_TIMEOUT issues.
rdt-cli (304 stars, public-clis) works without login — search, read
full posts, and comments all verified. Massive improvement.

Bilibili: add bili-cli (590 stars) as optional enhanced backend for
hot/rank/search/feed. yt-dlp remains for video metadata + subtitles.

Also fix UA string (was "agent-reach/1.0", now proper browser UA).

75 tests passing.
