AI Chat Screen for SwiftUI — Streaming LLM Chat UI

Description

> A drop-in, production-grade streaming chat screen for SwiftUI. Configure it

> with one `ChatConfig` struct and point it at any LLM endpoint — OpenAI-style,

> Anthropic-style, or any custom SSE server. Streaming tokens, typing indicator,

> empty and error/retry states, and full theming are already built. The included

> demo runs on a mock service, so it builds and streams with no API key.
