Add logrus as the primary logging framework with dependency injection
pattern. All errors now use WithError() for context, and structured
logging uses camelCase field names. Tag runtime service with service
field for better log organization.
- Add logrus dependency
- Update Runtime to accept logger via dependency injection
- Add WithLogger() option for logger configuration
- Log errors with WithError() for context
- Log async function failures with service context
- Document logging practices in AGENTS.md
Replace simple argument parsing with cobra to provide better CLI experience:
- Add 'execute' subcommand for running TypeScript files
- Add 'types' subcommand for printing TypeScript type declarations
- Add help text and error handling
- Update documentation with new usage examples
Add dependencies: github.com/spf13/cobra, github.com/spf13/pflag
