Usage: node play.ts [--raw <input>]

Run the Pullfrog action against an inline fixture. Host-side, in-process.
For a GHA-like Linux container, use \`pnpm gha play.ts […]\` instead.

Options:
  --raw <input>    raw string used as the prompt, or JSON object as full fixture
  -h, --help       show this message

Examples:
  node play.ts
  node play.ts --raw "Hello world"
  node play.ts --raw '{"prompt":"Hi","timeout":"5s"}'
