Initial Full-Stack Project Build (Electron Client & Node.js/MongoDB Backend & Authentication with Firebase)

[AkkuByte]

This pull request initializes the complete, fully functioning Vi-Notes application from scratch. Prior to this submission, the repository contained only the README.md and LICENSE files.

This PR introduces the entire full-stack architecture, including the Electron-based React frontend, Firebase authentication, a Node.js/Express backend, and a local MongoDB database integration.
