OptionallatestOptionallevelOptionalpatientOptionalvectorPer-run Pinecone vector stores (incl. the namespace existence check). When
hoisted, the describeIndexStats probe runs ONCE per run instead of once
per question. The full Safe<> is stored so the consumer's
existing error handling is unchanged; undefined = not hoisted (the runner
fetches per question, as before).
Run-scoped context hoisted once per chart-review run and passed into each question. Lets runners skip N redundant Supabase fetches that return the same data for every question.
