Revert to AsyncParsableCommand with parse-as-library

- Remove problematic AsyncAdapter that was causing continuation leaks
- Use AsyncParsableCommand directly with @main attribute
- Add -parse-as-library flag to Package.swift to enable @main
- This fixes the Swift continuation leak issue

Note: Integration tests still timeout in CI environment, likely due to
screen capture permissions or environment differences. The CLI works
correctly when run directly.
