Cold launch flow: no server-url -> /server-url. URL set, no token -> /login. Token present -> /home with shell. VersionGate runs once when the URL changes, hits /healthz, blocks if min_client_version > package version. /home is a placeholder until Task 14. Replaces Navigator.pushReplacementNamed in server_url_screen + login_screen with context.go now that go_router owns the routes.
