* Migrate HTTP servers from stdlib to Starlette/ASGI + uvicorn Replace Python stdlib http.server (ThreadedHTTPServer, BaseHTTPRequestHandler) with Starlette ASGI applications served by uvicorn across all three HTTP entry points. SSE endpoints use sse-starlette EventSourceResponse with async generators that bridge sync queue.Queue via run_in_executor(). Bridge SSE parser replaced with httpx-sse EventSource. - turnstone/server.py: Starlette app factory with create_app(), pure ASGI middleware (auth, rate limit, metrics, CORS), async route handlers, lifespan context manager for startup/shutdown. WebUI and ChatSession remain fully synchronous — worker threads unchanged. - turnstone/console/server.py: Same pattern, simpler (no ChatSession). Path params replace manual string slicing for node detail route. - turnstone/mq/bridge.py: _iter_sse_data() uses httpx_sse.EventSource instead of hand-rolled line parser. - Tests: All ThreadedHTTPServer fixtures replaced with starlette.testclient.TestClient via create_app() factories. - Docs: Updated architecture.md, api-reference.md, README.md, and PlantUML diagrams (03, 11) + regenerated PNGs. * Fix Copilot PR #11 review: TestClient cleanup, JSON error handling, SSE timeout - Close TestClient in teardown for TestConsoleAuth and TestConsoleLogin to avoid lifespan/resource leaks - Close TestClient via yield/finally in TestConsoleHTTPEndpoints fixture - Add _read_json() helper for safe JSON body parsing (returns {} on invalid JSON instead of 500, matching old stdlib handler behavior) - Apply same try/except pattern to console auth_login endpoint - Increase SSE queue.get timeout from 1s to 5s to align with sse-starlette ping interval, reducing executor task churn
