/**
 * Tool: add_attachment
 *
 * Generates a PDF/A-3 document with one or more embedded files
 * (ISO 19005-3 §6.8). Primary use case: Factur-X / ZUGFeRD electronic
 * invoices, where a structured XML payload is attached to a human-readable
 * PDF invoice with `relationship: 'Source'`.
 *
 * Implementation:
 *   - Delegates to pdfnative's `buildDocumentPDFBytes` with the `attachments`
 *     option and `tagged: 'pdfa3b'`. pdfnative validates that attachments are
 *     only allowed under PDF/A-3.
 *   - PDF/A-3 is enforced (pdfnative throws otherwise); the input schema
 *     does not expose the pdfA flag for that reason.
 *
 * Limitations:
 *   - Only document generation (not "add attachment to existing PDF"). The
 *     latter requires page-tree manipulation primitives not exported by
 *     pdfnative v1.2 and is tracked for v1.1 of pdfnative-mcp.
