## Files changed

- `crates/news-store/Cargo.toml` — added `chrono = { workspace = true }` for RFC3339 timestamp handling.
- `crates/news-store/src/lib.rs` — added `pub mod items` and re-exported `ItemRepo` + `InsertOutcome`.
- `crates/news-store/src/items.rs` — new file containing `ItemRepo`, `InsertOutcome`, `insert_if_new`, `search_fts`, and tests.

## Test coverage

- `items::insert_if_new_dedupes_on_source_and_link`: inserts the same `(source_id, link)` twice; first returns `Inserted`, second returns `AlreadyExists`; `raw_items` holds exactly 1 row.
- `items::tests::search_fts_returns_matching_items_ranked`: 3 distinct items, search for "election" returns the matching title.
- `items::tests::search_fts_no_match_returns_empty_vec`: search for "zzz_no_match" returns an empty `Vec` (not an error).
