/**
 * Detects document links on a page
 *
 * This function identifies document links by checking file extensions in both the pathname
 * and query parameters of URLs. It detects common document formats including PDF, Word,
 * Excel, and PowerPoint files.
 *
 * **Limitations**:
 * - Only detects documents with recognizable file extensions
 * - Does not detect documents served via content-type headers without extensions
 * - Does not make HEAD requests to verify content types
 *
 * @param page - The Puppeteer page to scan for document links
 * @param allowedTypes - Optional array of document types to filter by (e.g., ['PDF', 'MS_WORD'])
 * @returns Promise resolving to an array of detected document links
 *
 * @example
 * ```typescript
 * const documentLinks = await detectDocumentLinks(page);
 * // Returns all document links
 *
 * const pdfLinks = await detectDocumentLinks(page, ['PDF']);
 * // Returns only PDF links
 * ```
