[Enhancement] Add interactive demo and native Windows installer

[deangeckt]

📋 Problem statement

NEURD looks highly promising, but it is hard for new users to see the value quickly:

1. No live demo – beyond the figures in the paper, there is no interactive example that shows the workflow or outputs.
2. Docker-only install path – many non-developer researchers are unfamiliar with Docker and give up when images take a long time to pull or fail on their system.

💡 Proposed solution

A. Publish a lightweight interactive demo

• Host a small notebook (e.g., 1–2 MB mesh) on Binder, Voila, or Streamlit Cloud that:
  • Loads the sample mesh,
  • Runs a basic NEURD decomposition,
  • Visualises the output (screenshot + simple 3-D viewer).
• Link to it prominently in the README and docs.

B. Provide a Windows installer (.exe / MSIX)

✨ Expected benefits

• Lower adoption barrier: Users can experience NEURD in <2 min without installing anything.
• Broader audience: Windows-first labs (common in biology) can install with a familiar double-click flow.

Thanks for considering!
