- Replace custom Observable protocol and @Published with Apple's @Observable macro - Add withObservationTracking in renderToBuffer for automatic per-property dependency tracking - Add type-based @Environment(Type.self) and .environment(object) for observable objects - Add ObjectEnvironmentModifier for injecting observable objects into the environment - Add needsCacheClear flag to AppState for thread-safe cache invalidation - Add cross-platform test script (scripts/test-linux.sh) for Docker-based Linux verification - Add DemoAppHeader with system info display (OS, version, architecture) - Consolidate Example App: extract ImageDemoHelpers, KeyboardHelpSection, ValueDisplayRow - Add pre-push verification rule to CLAUDE.md - Verified on both macOS and Linux (swift:6.0 container), 1155 tests passing
