- crates/web/src/api/dto.rs -> api/models.rs (ArticleView/FeedView were
already models-shaped content, just not named models.rs)
- crates/core/src/scoring.rs's RelevanceInputs moves into
crates/core/src/models.rs alongside the other core domain types,
since it's built by score_article's callers, not score_article
itself
Also picks up an unrelated fmt fix in db/src/articles.rs (import
ordering) that landed on disk from elsewhere.
