feat(request): add --trace to show matched routes

[yusukebe]

Add --trace to hono request (idea from Yusuke). The output gets matchedRoutes: every middleware and handler that matched the request, with responded on the one that returned the response. Use it to debug an unexpected response in one command.

Implementation: wrap the app with a tracer middleware and read c.req.matchedRoutes / c.req.routeIndex — Hono's own APIs for this. On a 404 fallthrough the response comes from the notFound handler, so nothing is marked as responded then.

hono request -P /api/users/123 --trace
