Subject: [PATCH] fix(hierarchy): populate ResourceID from
 accessibilityIdentifier

iOS Compose surfaces testTag as accessibilityIdentifier. Previously
only resource-id and identifier seeded element.ResourceID, leaving
element.id empty for iOS Compose nodes and forcing specs to walk
attrs to recover stable identifiers.
