Stripped from vercel/chatbot (Apache 2.0): - Dropped @vercel/* packages and AI Gateway - Removed artifacts feature (code/text/sheet/image side panel) - Switched AI provider to @ai-sdk/openai-compatible -> EGBE LiteLLM - Replaced Vercel Blob upload with data URLs - Dropped Redis resumable streams and rate limiter (in-memory now) - Added Dockerfile (Next.js standalone) + entrypoint that runs migrations - Wired DATABASE_URL, EGBE_AI_API_URL/KEY, NEXT_PUBLIC_BASE_URL for app-deploy.sh
