WalkthroughUnknown-command detection now traverses the command tree, recognizes subcommands and aliases, and skips values for global options that take arguments. When help would mask an unresolved command token, the existing help-rendering hook reports the unknown-command error. ChangesNested help validation

🎯 Functional Correctness | 🟠 Major | ⚡ Quick win
Stop the walk at a leaf command so that its positional arguments are not reported as unknown commands.
The walk keeps going after current resolves to a command that has no subcommands. A positional argument of that leaf command then fails findRegisteredSubcommand. The argument reaches Line 280. If --help/-h comes later, the function returns the argument as an unknown command.
Example: testsprite test run <id> --help (or any leaf command that takes an argument, followed by --help). The beforeAll hook applies to subcommand help, so it fires here. The command exits 5 with VALIDATION_ERROR and does not print the leaf help, which should exit 0. This contradicts the objective that valid help targets still exit 0. The same failure also applies to help <group> <leaf> <arg>.
Report a token only when current actually has subcommands to resolve against.

Closing with #418 — the command surface is being rewritten and help/typo handling will be redone there. Thanks for the PR. |
