Expand auto-search to tech products, movies, series, comparisons

New pattern categories:
- Tech products: iPhone/Galaxy/Pixel/iPad + version numbers, specs,
  release dates, "neuestes Handy", Apple Vision Pro, Meta Quest, etc.
- Movies/series: Staffel/Season/Episode numbers, cast, ratings,
  neue Serie/neuer Film, IMDB, Rotten Tomatoes
- Product comparisons: "vs" with model numbers, "lohnt sich"
- Current leaders: Bundeskanzler, CEO, Präsident

These are high-hallucination topics where the AI's training data
is likely outdated — auto-search gives it fresh facts.

8 new tests (tech, movies, comparisons, leaders).
