Changed

• DeltaSkinNativeResolution — replaced hardcoded Swift enum with a JSON-backed registry (system-native-resolutions.json) so new system resolutions can be added without Swift source changes.

Added

• DeltaSkinScreen.nativeResolution — optional nativeResolution field in skin info.json screens, allowing per-screen AR overrides that take precedence over the system registry.
• DeltaSkinGameType.registryKey — stable string key (case name) used as the JSON dictionary key for resolution lookups.
