GitHub: resolving PR review threads requires GraphQL resolveReviewThread, not minimizeComment

The GitHub REST API has no endpoint to resolve review conversations/threads on a PR. The GraphQL minimizeComment mutation hides individual comments (collapsed with a reason) but does not mark the thread as resolved. To properly resolve a review thread, use the resolveReviewThread GraphQL mutation with the thread's node ID (obtainable from repository.pullRequest.reviewThreads).

Use gh api graphql -f query='mutation { resolveReviewThread(input: {threadId: "THREAD_NODE_ID"}) { thread { isResolved } } }' to resolve PR review threads programmatically.
