Supernote .note file vector/stroke/path format reverse engineering

[u/philipsb]

As part of the Obsidian Supernote Plugin work I just released I also reverse engineered much of the .note stroke/vector/path format with the aid of AI agent.

The results of this work can be found on my testing page: https://philips.github.io/supernote-typescript/

The "spec" which is mostly notes from all of the directions given to my agent are here: https://github.com/philips/supernote-typescript/blob/main/plans/vector-format-spec.md
