- Add i18n service wrapping pkg/i18n for translations via cli.T()
- Add log service with levels (quiet/error/warn/info/debug)
- Wire cli.Init() in cmd.Execute() with explicit service names
- Fix main.go to print errors to stderr and exit with code 1
- Update runtime.go to accept additional services via Options
Services use WithName() to avoid name collision since both are
defined in pkg/cli (WithService would auto-name both "cli").
