draft() emits ciceromark Formula node without required "value" field for inline {{% expr %}} formulas

[mttrbrts]

Reproduction

Repo: accordproject/cicero-template-library PR #484, template src/supply-agreement-loc.

grammar.tem.md (excerpt):

An initial payment of {{% importerLOCAmount / 2.0 %}} will be made immediately upon sight ...

model.cto:

@template
asset TemplateModel extends Clause {
  o Double importerLOCAmount
  ...
}

Driver:

const t = await Template.fromDirectory('./src/supply-agreement-loc');
await new TemplateArchiveProcessor(t).draft(data, 'markdown', {});

Observed

Error: Generated invalid agreement: ValidationException: The instance "org.accordproject.ciceromark@0.6.0.Formula" is missing the required field "value".: {
  "$class": "org.accordproject.commonmark@0.5.0.Document",
  ...
}

The engine produces a ciceromark@0.6.0.Formula node and then validates the output; the produced node is missing the required value field, so validation fails. The formula has nothing fancy — a single division of a model field by a constant.

Expected

draft() evaluates the inline formula, sets the resulting string on Formula.value, and produces a valid AgreementMark document.
