local 1614a61617 feat: add basic chat interface with MudBlazor and propose responses API integration

Install MudBlazor 9.2.0, replace Bootstrap layout with MudLayout/MudAppBar,
create Chat.razor with message list, text input, auto-scroll, and hardcoded
responses. Add ChatMessage shared model. Remove template pages (Counter,
Weather), move health check to /health. Include OpenSpec change artifacts
for the upcoming wire-responses-api work.

Raw Blame History

Why

The chat UI currently returns hardcoded responses. A local OpenAI-compatible proxy is running at localhost:8317 that exposes the Responses API (POST /v1/responses) backed by Anthropic Claude models. This change wires the chat to produce real AI responses via streaming, replacing the hardcoded stub.

What Changes

Add a chat endpoint to the API backend that proxies requests to the local Responses API
Stream tokens from the Responses API back to the WASM client as SSE
Update ChatApiClient with a streaming chat method
Replace the hardcoded response in Chat.razor with live streaming from the API
Add a "thinking" indicator while the assistant is responding
Disable input during streaming to prevent overlapping requests

Capabilities

New Capabilities
