Root path no longer 404s under the roadmap-visibility middleware

The feedback portal's root path (/) was getting caught by the roadmap-visibility middleware that gates project-scoped routes. The middleware was returning 404 because the root path has no :project param, and the visibility check assumed there was always one.

The middleware now short-circuits on the root path and lets it through to the actual root page (a redirect to marketing). Cold visits to feedback.roaderly.com resolve correctly instead of bouncing to 404.
