Extract reports unidentifiable boxes for human retakes

The vision prompt now returns {titles, unidentified}: boxes that look
like games but can't be confidently titled are reported (location
relative to identified neighbors, partial text, art notes) instead of
silently omitted. They land in data/unidentified.json keyed by photo,
and the end-of-run summary lists them — plus low-confidence reads —
with instructions to retake a closer photo and re-run. New --force flag
re-extracts everything; pre-feature raw caches (bare arrays) still
parse. Live run on IMG_4499 confirmed the flow and the low-confidence
list correctly flags the known "Hebarceos" misread.
