Quick start
import boto3, json
sfn = boto3.client("stepfunctions", endpoint_url="http://localhost:4566",
region_name="us-east-1",
aws_access_key_id="test", aws_secret_access_key="test")
sm = sfn.create_state_machine(Name="demo",
RoleArn="arn:aws:iam::000000000000:role/r",
Definition=json.dumps({"StartAt":"Done","States":{"Done":{"Type":"Pass","End":True}}}))
sfn.start_execution(stateMachineArn=sm["stateMachineArn"])

- Executions metrics (ExecutionsStarted/Failed/Duration) are not emitted.
- Use SFN_MOCK_CONFIG to mock Task state responses for Lambda/service calls.
