Refresh skills on an existing app
Do not re-run nuvyn init on a tree that already exists. After you update the global CLI (dotnet tool update -g NuvyntraLabs.Nuvyn.Cli --source https://api.nuget.org/v3/index.json), refresh the app's slash files:
cd ClinicApp
nuvyn update
nuvyn update --agent cursorupdate overwrites .nuvyn/templates/, .nuvyn/reference/, and the agent command files. It leaves host code, specs/, .nuvyn/constitution.md, and .nuvyn/adopt-report.md alone. It does not change PackageReference versions. --vertical is not in 1.2.
nuvyn check inside a greenfield app also proves the host still uses MVVMExpress + UIKit + HttpForge + FormValidation + KeyboardManager — and nothing else from the catalog. On an adopted app it prints the inventory and skips that proof. Both paths run maui-dev doctor when MauiDev is installed.
