 * Manages storage of batch processing state with automatic context detection.
 *
 * This class abstracts the storage mechanism for batch processing state,
 * automatically choosing between InvokeStore (when in Lambda context) and
 * fallback instance variables (when outside Lambda context). The decision is
 * made at runtime on every method call to support Lambda's concurrent execution
 * isolation.
