fix: Add visionOS to platform checks (#144)

* fix: Add visionOS to platform check for native providers

The `#if os(...)` guard on the native app version and bundle identifier
providers was missing `os(visionOS)`, causing a build error on visionOS:
"Cannot find 'nativeAppVersionProvider' in scope".

* fix: Add visionOS to DeviceIdentifier platform check

Same issue — the `#if os(...)` guard was missing `os(visionOS)`,
causing 'data_blocking' to be unavailable on visionOS.
