Commit Message: Merge PDFs: add CLI for merging/inserting PDFs with validation; preserve original helpers
Description & Annotation:
This commit extended the Merge PDFs project by:
Adding a CLI to merge any number of PDFs in one command
Supporting insertion of a PDF at a chosen index
Validating file existence and type
Preserving the original helper functions for backward compatibility
This contribution matters because it makes the project scalable and flexible. Instead of merging hardcoded test files, users can now merge their own PDFs safely and reliably. It highlights my ability to modernize legacy code while maintaining backward compatibility.
