+fix(cli): make native install source description platform-aware
+
+On macOS, script installs via the official install.sh are detected as
+"native" but the message hardcoded "native (windows). Auto-update is not
+supported on this platform." even though native non-Windows installs do
+support auto-update. Show "native (windows)" only on win32 and just
+"native" elsewhere.
