Function the driver calls to actually execute the child flowchart.
Returns a Promise resolving to the chart's terminal value (whatever
FlowChartExecutor.run() resolves with), or rejects on failure.
Drivers wrap this in their own try/catch so the rejection routes to
handle._markFailed() instead of escaping into the parent context
(passive-recorder rule).
