Add SwiftFormat, restructure SwiftLint, and fix Sendable warnings

Replace Xcode build phase SwiftLint with CLI-based enforcement via
GitHub Actions CI. Add SwiftFormat for consistent code formatting
with .swiftformat config. Move .swiftlint.yml from NativeAppTemplate/
subdirectory to repository root with simplified rules. Add CHANGELOG.md
following Keep a Changelog format. Fix Swift 6 Sendable capture warnings
in NFCManager and ItemTagDetailViewModel using @preconcurrency import
and nonisolated(unsafe). Fix ambiguous #require macro calls in test
assertions.
