runGenerateRoutes function

void runGenerateRoutes(List<String> args)

river_cli generate routes — discovers every scaffolded feature and regenerates lib/app/routes/app_routes.dart and route_page.dart from scratch, so the route table always matches what is on disk.

This OVERWRITES the routing files. Custom guards/redirects/nested routes are not preserved — use it as a repair/sync command. --dry-run previews only.
