Hono treats a trailing slash as a distinct path, so /users and /users/ do not both match

Hono's routers match paths literally. A route registered for /users does not answer /users/ and returns 404 instead. Because clients, link generators and framework helpers disagree about trailing slashes, this appears as an intermittent 404 affecting one caller while every other path works.
The built-in trailing slash middleware trims a trailing slash by redirecting to the version without it, and a companion middleware appends one instead. Pick a direction and register the middleware before the routes. Both issue a 301, which browsers cache aggressively, so reversing the choice later needs a plan for the cached redirects already in the wild. The root path is a single slash and both middlewares leave it alone.
