Initial scaffold: full-stack mRemotify monorepo

Sets up the complete mRemotify project — a browser-based remote
connection manager — with a working pnpm workspace monorepo:

Frontend (React + TypeScript + Vite + Ant Design 5):
- Login page with JWT auth
- Resizable sidebar with drag-and-drop connection tree (folders + connections)
- Tabbed session area (SSH via xterm.js, RDP via guacamole-common-js)
- Connection CRUD modal with SSH/RDP-specific fields
- Zustand store for auth, tree data, and open sessions

Backend (Fastify + TypeScript + Prisma + PostgreSQL):
- JWT authentication (login + /me endpoint)
- Full CRUD REST API for folders (self-referencing) and connections
- AES-256-CBC password encryption at rest
- WebSocket proxy for SSH sessions (ssh2 <-> xterm.js)
- WebSocket proxy for RDP sessions (guacd TCP handshake + bidirectional relay)
- Admin user seeding on first start

Infrastructure:
- Docker Compose: postgres (healthcheck) + guacd + backend + frontend/nginx
- nginx: serves SPA, proxies /api and /ws (with WebSocket upgrade) to backend
- .env.example with all required variables documented
