Prompt loop over ambiguous/unmatched rows: pick a candidate (table with
owned/rank), skip, reject, enter a manual BGG id, or free-text re-search
via the cached client. Approvals attempt version resolution from the
title's edition cues, degrading to version_unknown when the API is
unreachable (no token yet). Optional, skippable version pass for
version_ambiguous rows. Every decision rewrites matches.csv atomically,
so q/Ctrl-C/EOF mid-session loses nothing. Tests drive the loop with
scripted input against a synthetic matches.csv and the fixture cache.
