Remove-from-catalog: a third durable curation store

Titles that aren't games (misread box art, out-of-scope items) can now
be removed outright: a danger button in the catalog's edit panel posts
/api/remove-title, which drops the line's matches rows (veto'd ones
too — removal is the human explicitly discarding the line), records the
decision photo-scoped in data/title_removals.json, and replays
titles.json. Every rebuild filters removed sightings after edits and
before dedupe, so re-extraction cannot resurrect them; undo by deleting
the record from the store. The three stores now share one scoped-record
parser and recorder.

 - Base game vs. expansion vs. new edition is the top failure mode — bias matching toward `ambiguous` over auto-match ("Wingspan Europe" must not match base Wingspan).
 - Editions/versions matter: Eric owns multiple editions of some games — each is a separate collection entry (keyed by `collid` on BGG). Never guess a version: no legible cues → `version_unknown` and a version-less collection entry.
 - Normalize titles (casefold, strip punctuation/articles, special chars like é/&/:) identically on both sides of a match; dedupe across photos but keep `source_photos` provenance.
-- **Human curation is durable**: `data/title_splits.json` (photo-scoped split-into-copies decisions, honored by extract's dedupe AND resolve's dedupe) and `data/title_edits.json` (corrected reads/cues, applied before dedupe on every titles.json rebuild) persist forever. Row-level decisions persist via the `dedupe_veto` column — edits never drop veto'd rows (a rename retitles them in place).

 - **RPGs are local-only citizens**: when the board-game search runs dry, resolve falls back to `type=rpgitem` (same geekdo API/token). Matched rpgitems enrich into the library but diff routes them to `local_only` — they must never reach `to_add.csv`/upload (their collection lives on RPGGeek, out of scope).
 - Detailed BGG API behavior (202 queueing, collection-endpoint quirks, endpoints): use the `bgg-api` skill. **If the spec's BGG behavior changes, update the `bgg-api` skill to match** — they must not drift.
