- Fixes #1509. The CLI's own help text tells users to run `container help <subcommand>`, but every form of that results in an error. - Added a captured subcommand path, walked Application`'s `subcommands` + `groupedSubcommands` tree (matching `commandName` and `aliases`), and printed `Application.helpMessage(for:)` for the resolved target. Empty path keeps existing plugin-aware top-level help; unknown path throws `ValidationError`.
