Add comprehensive README.md documentation

[Copilot]

Repository lacked root-level documentation. Added README.md covering project setup and architecture.

Changes

• Created /README.md with:
  • Project description: Riverflow, a remote recording studio with WebRTC capabilities
  • Technology stack: React 19/TypeScript/Vite frontend, Node.js/Express/Socket.IO backend, SQLite persistence
  • Installation and configuration instructions for both frontend and backend
  • Development workflow: backend on port 5000, frontend on port 5173
  • Project structure overview showing controllers, routes, components hierarchy
  • Security note: JWT_SECRET replacement required for production

Structure

riverside---clone/
├── backend/          # Node.js + Express + Socket.IO (port 5000)
├── frontend/         # React + TypeScript + Vite (port 5173)
└── README.md         # Project documentation (new)

The README provides immediate onboarding for new contributors and documents the monorepo structure with separate frontend/backend services.
