/**
 * Usage notes:
 *
 * 1. The Flow Executor will create an AbortController internally based on the timeout configuration.
 * 2. For each step execution, the AbortController's signal is passed to the JsonRpcHandler.
 * 3. The RequestStepExecutor handles AbortError exceptions automatically.
 * 4. End users only need to:
 *    - Configure timeouts at flow and/or step level
 *    - Optionally provide fallback values for timeout cases
 *    - Implement a JsonRpcHandler that respects the AbortSignal
 *
 * The FlowExecutor takes care of the rest, including:
 * - Creating and managing AbortController lifecycle
 * - Ensuring signal propagation to handlers
 * - Proper error handling and timeouts
