v18.1.5

A search fix. The brain format (version: 7), bf.yaml, the reply schemas, the packaged skills and the search cache are unchanged. Upgrade with uv tool upgrade brain-framework (or update a brain's pin); a copied prompt-context.py hook can take the example's new word list.

Fixed

• Search drops other, others and another, and the French autre, autres, ma and ta, like other function words. In a mostly English brain, Pourquoi Kotlin plutôt qu’un autre langage ? ranked first a short French note that only shared autres with the question, a rare word that outweighed the subject; the note about Kotlin now ranks first. A query made only of such words still searches them literally. The example prompt-context.py hook mirrors the list.
