/**
 * Create a distill turn stage.
 *
 * The distill stage reads the full builder conversation (user↔reviewer
 * transcript) and produces clean single-author prose representing the user's
 * final, settled argument. The prose is then fed into the existing ingestion
 * pipeline (by the consumer) to yield a `TParsedArgumentResponse` shaped
 * exactly like ingested arguments — same enrichment, same parser, zero drift.
 *
 * The whole transcript reaches this turn via the existing chaining
 * (`previousResponseId` / `userMessage`) — chained off the latest response,
 * not a re-rooted pre-review response. The distill prompt uses reviewer
 * questions only as context to interpret the user's (often terse, reactive)
 * answers; the ingestion pipeline keeps receiving single-author text and is
 * never told it originated from a conversation.
 *
 * This is the terminal turn — seals the conversation via `onClose`.
 * No further turns are allowed after this.
 *
 * `retry.maxAttempts: 1` — distillation failure is a content issue, not a
 * transient one. Retrying the same prompt will not help.
