Unknown Nasiko status argument

Error message

Unknown Nasiko status argument: ${argument}

What it means

The `status` subcommand only accepts --json and --install-dir. parseStatusArguments throws this error for any other token, keeping the status parser strict so typos fail fast instead of being ignored. The offending argument is interpolated into the message.

Solutions

1. Use only --json and --install-dir <path> with the status command.
2. Remove flags like --version that belong to install/uninstall.
3. Fix typos in the flag name.
4. Check the usage text printed by the script for the exact accepted flags.

Example fix

// before
node scripts/nasiko.js status --version v0.1.0
// after
node scripts/nasiko.js status --json

const ALLOWED = new Set(['--json','--install-dir']);
const bad = args.filter(a => a.startsWith('--') && !ALLOWED.has(a));
if (bad.length) throw new Error(`status accepts only --json and --install-dir, got: ${bad.join(' ')}`);

try {
  runNasiko(['status', ...statusArgs]);
} catch (err) {
  if (err.message.startsWith('Unknown Nasiko status argument')) {
    console.error('Use only --json and --install-dir with nasiko status.');
  } else throw err;
}

When it happens

Trigger: Running `nasiko status --verbose`, `nasiko status -h`, or a mutation-only flag like `--version v0.1.0` against the status command; any unrecognized token in the status argument list.

Common situations: Copying flags from the install/uninstall command into status (e.g. --version, which status does not need); typos like --instal-dir; passing subcommand-agnostic flags like --help that this minimal parser does not implement.
