cleanup: move test_document_extracted directory to history

Move test output directory from md-package extract command to history archive.
This was manual test output from packaging functionality testing.

What Was Moved:
- test_document_extracted/content.md: Sample extracted markdown content
- test_document_extracted/package.json: Package metadata for MDZ format
- Added README.md documenting the archived test output

Rationale:
- Test output artifact from manual testing (created 2025-10-14)
- No longer referenced by any current code
- Packaging functionality properly tested elsewhere
- Part of comprehensive root directory cleanup

Project Status:
- ✅ Root directory now clean of all test output artifacts
- ✅ Development files cleanup 100% complete
- ✅ All test artifacts properly archived with documentation
