v0.4.0

Added

• Middleware: WebSocket support for TraceIDMiddleware and AccessLogMiddleware. Request ID is read from the WebSocket upgrade request headers (or generated), set in context for the connection lifetime, and reset on close. Access log records WEBSOCKET {path} - 101 - {latency}ms. Lifespan scope is passed through without request_id or access log.
• Context: request_id_scope(request_id) context manager to set and reset request ID on exit (used internally by middleware; available for custom ASGI apps that need the same semantics).

Changed

• Middleware: Replace BaseHTTPMiddleware with Pure ASGI implementation for TraceIDMiddleware and AccessLogMiddleware. Request handling uses scope / receive / send directly, improving latency and stability under load. Module docstring links to ASGI spec for scope types (http, websocket, lifespan).
• Makefile: make bench-compare supports an optional run ID (e.g. make bench-compare ID=0002); default remains 0001.
• Docs: Clarify uv usage and scaffold flow in installation and getting-started; reduce redundancy in CLI and scaffold docs.
• Template: Use async httpx client in standard-3tier generated tests.

Other

• Tests: Add middleware tests for WebSocket and lifespan behavior; add coverage for response helpers, HTTP client hooks, and schemas ensure_utc.
