apple_framework, apple_application, and apple_test_bundle have moved from schema-only stubs to real Starlark implementations. apple_framework now emits a real dylib with an Info.plist and module.modulemap; apple_application links a real executable, embeds dependent frameworks, and can be launched with once run; and apple_test_bundle produces a real .xctest bundle linking XCTest. These were previously placeholders that only generated a directory shape.
