/**
 * Fetch GraphQL node IDs and thread resolution status for review comments.
 *
 * This function bridges the gap between GitHub's REST API and GraphQL API
 * to provide enhanced comment tracking capabilities. It maps REST comment IDs
 * to GraphQL thread IDs and tracks which threads are resolved.
 *
 * ## Why This Is Needed
 *
 * GitHub's REST API provides comment data but lacks some advanced features:
 * - No direct thread resolution status in comment objects
 * - No GraphQL node IDs for advanced operations
 * - Limited thread-level information
 *
 * The GraphQL API provides:
 * - Thread-level resolution status (`isResolved`)
 * - GraphQL node IDs for advanced operations
 * - Better thread management capabilities
 *
 * ## GraphQL Query Structure
 *
 * The query fetches review threads with:
 * - Thread ID (GraphQL node ID)
 * - Resolution status (`isResolved`)
 * - Associated comments with database IDs
 * - Pagination support for large PRs
 *
 * ## Mapping Strategy
 *
 * 1. **Fetch Threads**: Get all review threads for the PR
 * 2. **Map Comments**: Link REST comment IDs to GraphQL thread IDs
 * 3. **Track Resolution**: Record which threads are resolved
 * 4. **Early Exit**: Stop when all requested IDs are mapped
 *
 * ## Error Handling
 *
 * If GraphQL fails, the function returns empty maps rather than throwing.
 * This ensures the REST API fallback continues to work, though with
 * reduced functionality (no thread resolution status).

 * @param octokit - GitHub API client instance
 * @param pr - Pull request information
 * @param pr.owner - Repository owner
 * @param pr.repo - Repository name
 * @param pr.number - Pull request number
 * @param commentIds - Array of REST comment IDs to fetch node IDs for
 * @returns Promise resolving to node ID map and resolved thread IDs
 *
 * @example
 * ```typescript
 * const { nodeIdMap, resolvedThreadIds } = await fetchReviewCommentNodeIds(
 *   octokit,
 *   { owner: 'owner', repo: 'repo', number: 123 },
 *   [12345, 12346]
 * );
 *
 * // Check if a comment's thread is resolved
 * const threadId = nodeIdMap.get(12345);
 * const isResolved = resolvedThreadIds.has(threadId);
 * ```
