Step 7: Multi-format Export Generation (Thin Orchestrator)

This step generates exports in multiple formats (JSON, XML, GraphML, GEXF, Pickle).

Architectural Role:
    This is a "thin orchestrator" - a minimal script that delegates core functionality
    to the corresponding module (src/export/). It handles argument parsing, logging
    setup, and calls the actual processing functions from the export module.

Pipeline Flow:
    main.py → 7_export.py (this script) → export/ (modular implementation)

How to run:
  python src/7_export.py --target-dir input/gnn_files --output-dir output --verbose
  python src/main.py  # (runs as part of the pipeline)

Expected outputs:
  - Multi-format exports in the specified output directory
  - JSON, XML, GraphML, GEXF, and Pickle format files
  - Comprehensive export reports and summaries
  - Actionable error messages if dependencies or paths are missing
  - Clear logging of all resolved arguments and paths

If you encounter errors:
  - Check that export dependencies are installed
  - Check that src/export/ contains export modules
  - Check that the output directory is writable
  - Verify export configuration and format requirements
