Branching out my simple converter script to a full-fledged project.

The goal is to create a powerful Markdown parser, testing several approaches along the way, that can handle various formats and convert them into the cleanest Markdown possible.
Possibly leveraging AI for post-processing.

This project is important as it is the foundation to feed clean data into AI workflows.
