Add JARVIS - Self-hosted AI assistant platform

[hyhmrright]

I'm adding JARVIS to the Open Source Projects section.

JARVIS is an open-source, self-hosted AI assistant platform that uses Vue 3 as its frontend:

• Vue 3 frontend with TypeScript, Pinia state management, vue-i18n (6 languages), and Vue Router with auth guards
• Real-time SSE streaming chat using native fetch + ReadableStream
• Axios instance with request/response interceptors for JWT auth and auto-logout
• Full-stack: FastAPI backend with LangGraph ReAct agents, RAG knowledge base (Qdrant), multi-LLM support (DeepSeek/OpenAI/Anthropic), plugin SDK, and Docker Compose one-command deployment
