Real extraction from shelf photos; test title list moves to tests/data

First live vision run: 4 shelf photos -> 27 unique titles with edition
cues (publishers, Bookcase Game/Designer's Edition wording, art notes);
cross-photo dedupe merged repeat sightings. data/titles.json now holds
real pipeline data, so the hand-typed resolve test list moves to
tests/data/titles.json (tests and record_fixtures updated), and the
matches.csv generated from stub fixtures for that list is removed —
the real resolve run will regenerate it once the BGG token arrives.
