/**
 * ODF archive-safety guard.
 *
 * Reuses docx-core's format-agnostic `inspectZipEntries` for the zip-bomb / entry
 * limits (entry count, single-entry size, total uncompressed size, compression
 * ratio), and additionally asserts the package declares the OpenDocument text
 * mimetype. Returns a plain result; the MCP layer maps failures to tool errors.
