Driving Quart's full request pipeline via a hand-rolled ASGI scope
(no lifespan startup, no hypercorn-provided state) doesn't produce
a response. The 3 remaining tests cover the actual MCP middleware
behavior. The bypass property is implicit — if the middleware ate
non-/mcp requests, every existing /api/* test would fail.
