契约

• ArgParser parses hierarchical subcommands into nested ArgResults accessible via results.command, where option values and positional rest arguments are scoped to their respective command level.
• assert top-level ArgResults has null name and results.command holds child ArgResults with the subcommand name
• assert subcommand option values are stored in results.command and querying them on the parent throws ArgumentError
• assert positional arguments supplied after subcommands belong to the innermost command rest list leaving parent rest empty
• assert options defined on a subcommand that precede the subcommand token on the command line throw FormatException
• assert parsing without subcommands sets results.command to null and routes positional tokens to the root rest list
• assert unconfigured command words are treated as positional arguments in rest rather than populating results.command
