workflow

Run a multi-step skill workflow declared in a workflow YAML file. Use when the user asks to "run the workflow at <path>", "execute workflow <name>", "run the <name> workflow", "chain these skills", "compose <skill-a> and <skill-b>", or supplies a path to a `.yaml` workflow definition. Arguments follow a `key=value` grammar: the first positional value is the workflow file path, remaining `key=value` pairs are workflow inputs. The runner executes steps strictly in order, halts on the first non-zero exit, and writes a summary JSON to the workflow directory.
