fix: stop spawning duplicate villains from descriptions in the name field

Root cause of "4 entries for the same person": physical descriptions were being
passed as `name`, creating a new *named* player each time the wording drifted
(exact-name match can't dedupe near-identical sentences, and the merge scan only
looks at descriptor embeddings).

- add_read: a `name` that looks like a description (comma-listed / long / has
  appearance words) is rerouted to the descriptor path so it dedupes.
- descriptor reads that are ambiguously close to an existing villain now file a
  merge_candidate to the review queue instead of leaving a silent duplicate.
- distinctiveness() reworked: recognizes specific content (proper nouns/brands,
  feature lists) as distinctive even when a generic word like "shirt" is present —
  the old list-only heuristic scored "Filipino, Fox Racing hat, DKNY shirt" as
  generic and gated it out.
- Cash card: name = real handle ONLY; the look goes in descriptor as a few
  distinctive tags, and use name_villain to fuse a name onto a described player.

Full suite 157 green.
