Previously, 'opal -h', 'opal --help', and 'opal help' would show the
list command help instead of the root command help. This was because
the argument preprocessing logic would rewrite these as 'opal list -h'
before Cobra could handle them.
Now we detect help flags/command before preprocessing and let Cobra
handle them naturally. This ensures:
- 'opal -h' and 'opal --help' show root help
- 'opal help' shows root help
- 'opal help <command>' shows command-specific help
- 'opal <command> -h' still shows command-specific help
- All existing flexible syntax continues to work
