/**
 * Core PDF decomposition logic for already-loaded PDF documents
 *
 * Decomposes a PDF document and extracts all content including:
 * - Text content with positioning and formatting
 * - Images (if extractImages option is enabled)
 * - Document structure and metadata
 * - Page-level information (dimensions, rotation, etc.)
 *
 * @param pdfDocument Already loaded and processed PdfDocument instance
 * @param options Optional configuration for decomposition process
 * @param progressCallback Optional callback for progress updates
 * @param errorCallback Optional callback for error notifications
 * @returns Promise resolving to DecomposeResult with pages array
 *
 * @example
 * ```typescript
 * import { pdfDecompose } from 'pdf-decomposer/core'
 *
 * // Load PDF first
 * const pdfProxy = await PdfLoader.loadFromBuffer(buffer)
 * const pdfDocument = new PdfDocument(pdfProxy)
 * await pdfDocument.process()
 *
 * // Then decompose with progress tracking
 * const pages = await pdfDecompose(pdfDocument, {
 *   startPage: 1,
 *   endPage: 10,
 *   elementComposer: true,
 *   extractImages: true
 * }, (state) => {
 *   console.log(`Progress: ${state.progress}% - ${state.message}`)
 * })
 * ```
