BREAKING CHANGES

• state machines whose JSONata expressions reference a bare
  top-level name are now rejected at creation, as on AWS. Anchor the reference
  with $states.input. for input or $ for an Assign variable.

• fix(stepfunctions): parse a JSONata payload key named after an ASL field

The deny list of fields AWS does not parse as JSONata was applied to every
key at every depth, so a payload key named Next, Comment, Resource, Retry,
Default, ErrorEquals, Credentials, Branches, ItemProcessor or Iterator hid
its expression. AWS parses a payload whole: Assign: {"Next": "{% phone %}"}
and Arguments: {"Payload": {"Comment": "{% phone %}"}} are both refused
with Reference to 'phone' at the top level is not supported. The deny list
now stops applying once the walk enters Output, Assign, Arguments,
ItemSelector or BatchInput.

The same walk refused ItemReader.ReaderConfig.CSVHeaders, which holds
literal column names: validate-state-machine-definition returns OK for it
and create-state-machine stores the machine, so CSVHeaders joins the list.
