runDeployCommand function

Future<int> runDeployCommand(List<String> args, { IOSink? outSink, IOSink? errSink, Map<String, String>? environment, DeployCommandRunner? commandRunner, })

Runs the deploy CLI command and returns a process-compatible exit code.

Returns 0 for help and successful dry-runs, 64 for invalid arguments, and 1 for runtime failures while resolving options.
