document workflow capabilities

Workflow methods should include comments that document their orchestration capabilities and data access patterns. This helps developers understand the available temporal execution features and interaction methods.

Key areas to document:

• Data access patterns (bindings via this.env, parameters via event.payload)
• Orchestration capabilities (waiting for external events, human approval, webhooks)
• External interaction endpoints (HTTP POST patterns for submitting data to workflow instances)

Example:

async run(event, step) {
    // Can access bindings on `this.env`
    // Can access params on `event.payload`
    
    const files = await step.do("my first step", async () => {
        // Fetch a list of files from $SOME_SERVICE
        return { files: [...] };
    });
    
    // You can optionally have a Workflow wait for additional data,
    // human approval or an external webhook or HTTP request before progressing.
    // You can submit data via HTTP POST to /accounts/{account_id}/workflows/{workflow_name}/instances/{instance_id}/events/{eventName}
}

This documentation pattern ensures workflow code is self-explanatory about its durable execution capabilities and helps maintain clarity in complex orchestration scenarios.
