feat(examples): add progress feedback for batch parsing

[however-yir]

Summary

• add explicit per-file progress output in examples/example.py ([idx/total] format)
• print a final summary with processed/skipped/failed/total counters
• keep behavior unchanged aside from user feedback

Why

Issue #136 asks for feedback while processing PDF/document batches. This improves visibility during long runs without changing API behavior.

Closes #136

This is a good one, why dont we add a tqdm for every request that num of images or pages of pdf > 1

@JaredforReal Thanks for the suggestion — implemented in the latest commit.\n\nUpdated to add progress for multi-input runs, and for PDF inputs the progress is weighted by page count (via ) so multi-page PDFs are reflected in progress as well.\n\nCould you please take another look?

Updated examples/example.py to add tqdm progress for multi-input runs, and for PDF inputs the progress is weighted by page count (via pdfinfo) so multi-page PDFs are reflected in progress as well.
