v0.16.0

Queue handlers can now bound an individual external operation with the worker's deterministic scheduler:

try {
  const result = await control.withTimeout(30_000, (signal) => {
    return executeTool(input, { signal });
  });

  actions.emit("tool.completed", result);
} catch (error: unknown) {
  actions.emit("tool.failed", describeFailure(error));
}

• The operation signal aborts on either its deadline or active lease cancellation.
• Timeouts reject with WorkOperationTimeoutError. Catch them to commit an application outcome, or leave them uncaught to use normal work retry behavior.
• withTimeout(...) controls timing and cancellation; it is not an execution sandbox. Pass only the capabilities the operation needs and keep external effects idempotent.
