Photo-title fixture set + resolve baseline; language-only cues skip fetch

Data-driven stub XML for all 27 extracted titles (searches incl. empty
results for the long Avalon Hill/SPI box titles, truncated-head retry
queries for later, tie-break stats with publisher links, version lists
aligned with the real collection objectids). Language-only cues no
longer trigger a versions fetch — language can't reach the plausibility
threshold alone, so the request would always be wasted; it still scores
when stronger cues exist. Baseline resolve: 22 auto, 1 ambiguous
(Wiz-War editions), 4 unmatched (the long box titles — next commit).
