[Request] [language/nasm]

Request for a tutorial on NASM. I am going to be learning it elsewhere for now, so if it is not available by then I will attempt to help.

The issue names no files, tests, or entry points; it only requests a tutorial on NASM. Review the repository's existing tutorial structure and contribution guidance first, then define the tutorial's scope and validation approach. Done means a complete NASM tutorial in the project's established format.
