 * categories.ts) and individually soft-fails to 0, so this is safe to call
 * from layouts and server components on every render.
 *
 * `total` is the number of distinct actionable items: suggested_match is a
 * fast path over transactions already counted in book_transaction, so it is
 * excluded to avoid double-counting (see lib/worklist/types.ts).
