Stop Smart Search recommending the wrong movie / CAMs

TPB search is fuzzy: querying "Toy Story 5" returns Toy Story 4/3/… plus the
only real 2026 copies, which are CAM/Telesync. The LLM rejected them all, then
fallbackReleases picked the most-seeded (Toy Story 4), ignoring title/year.

Two deterministic guards:
- prefilter now drops low-quality source tags (CAM/TS/TELESYNC/SCR/…) via a
  token match, so neither the LLM nor the fallback can surface them.
- findReleases requires the confirmed TMDB year in a movie's release name, so a
  fuzzy match can't cross to a different film. If nothing survives, return no
  options and tell the user it may be unreleased / only CAMs exist.

Verified: "Toy Story 5" now returns 0 options (was Toy Story 4); Night of the
Living Dead (1990) still recommends its 1080p x265 pack.
