Standardize CI workflows

- Update swift-format to Swift 6.2
- Standardize swiftlint to simple variant
- Remove Windows CI jobs (too flaky)
- Add README validation where missing
- Add missing workflow files

All swift-* packages now have consistent CI configuration:
- Test on minimum Swift version (macOS)
- Test on Swift 6.2 (macOS & Ubuntu)
- README validation tests
- No Windows support
