docs(positioning): reframe unarr around download/stream/transcode, drop misleading search-first wording

Old copy claimed unarr was a "torrent search" tool. unarr's real job is
downloading (torrent + debrid + usenet), streaming via local HLS, transcoding
with ffmpeg+HW accel, and library management. Search just queries the
torrentclaw.com catalog — secondary feature, not the identity.

- root cobra Short/Long now lead with download/stream/transcode and list the
  three backends + WireGuard + Cloudflare Funnel
- README hero + subheading mirror the same positioning
- DOCKERHUB hero updated to match
- "Search & Discovery" group → "Catalog & Discovery" (search still grouped,
  but framed as catalog browsing not product identity)
