Explicit v1 limitations

The following are not silently supported:

• arbitrary after, from, to, or depends-on DAG edges;
• structural loops, durable for-each, batching, race, or first-success groups;
• declarative <http>, <db>, <storage>, or other capability tags in steps;
• per-step timeout attributes;
• parallel on-error="continue";
• multi-step direct children inside <parallel>;
• nested forks inside a fork-owned branch subtree;
• npm imports, package registry modules, default exports, CommonJS, or dynamic module installation;
• arbitrary structural custom tags or child-generating components;
• custom provider triggers (kind="trigger");
• external schema-file references;
• context.run, context.env, secret enumeration, or bracket-style WOML references;
• a JavaScript woml.resume() API;
• synchronous workflow calls that wait through Human Approval;
• automatic parent-to-child cancellation propagation or compensation/sagas;
• NoSQL/document database drivers;
• services.queue;
• services.slack.send(); and
• a managed multi-node/distributed production control plane.

Use local JavaScript for ordinary in-step loops and transformations. That does not create durable per-item nodes, retries, or inspection.
