/**
 * Converts a PDF (URL or ArrayBuffer) into HTML using LiteParse's spatial text

 * @param pdfURLOrBuffer - URL to a PDF file or buffer from fs.readFile
 * @param options.addPageNumbers default=false - Adds `[n]` markers at each page boundary
 * @param options.addCitation default=true - Populates `title`/`author` from PDF metadata
 * @param options.liteParseOptions - Passed through to the `LiteParse` constructor;
 *   defaults to `{ ocrEnabled: false, ocrFailureFatal: false }` (use detectPdfNeedsOcr
 *   to decide when a document is worth re-parsing with `ocrEnabled: true`)
 * @returns `{ html, title, author, format: "pdf" }`, or `{ error }` on failure
 * @category Extract
