Initial commit

PyMeshCore GUI is an open-source desktop application for interacting with the MeshCore network.
It focuses on **chatting, prototyping, and development** on top of MeshCore, with an emphasis on
desktop workflows and developer accessibility.

The project is built using PySide6 (Qt for Python) and meshcore-py.
