/**
 * Derives a shepherd `MergeStatusResult` from raw PR data.
 *
 * `pr.state` is passed through unchanged; `iterate` handles the cancel action
 * for non-OPEN (merged/closed) PRs — this function does not branch on it.
 *
 * Interpretation order for `status` — first match wins:
 *   1. mergeable == CONFLICTING       → CONFLICTS (hard conflict even for drafts)
 *   2. blockingBotReviewInProgress        → BLOCKED
 *   3. mergeStateStatus DIRTY         → CONFLICTS (GitHub merge conflicts, even for drafts)
 *   4. isDraft                        → DRAFT
 *   5. mergeStateStatus BEHIND        → BEHIND
 *   6. mergeStateStatus BLOCKED / HAS_HOOKS → BLOCKED
 *   7. mergeStateStatus UNSTABLE      → UNSTABLE
 *   8. mergeStateStatus UNKNOWN       → UNKNOWN
 *   9. mergeStateStatus CLEAN         → CLEAN
