Under what scenario does a node not have a name property? If there is no scenario, and we have checks elsewhere, let's remove this condition.

You're right — there's no such scenario. name is a required field on IElementDefinition, which IOptionalDefinition, IConditionalDefinition, and IWithDefinition all extend. Removed the unnecessary check in 3f9a552.

The `age` property is marked as `optional` in the Concerto model but was
used directly as `{{age}}` without an `{{#optional}}` guard. After PR accordproject#53
introduced stricter compile-time checks for optional properties, this
causes the test to fail with: "Optional properties used without guards: age"
Wraps the bare `{{age}}` reference in `{{#optional age}}{{this}}{{/optional}}`
to align with the new validation rules.
Fixes accordproject#112

Description
Add compile-time type checking for optional properties in TemplateMark templates. When an optional property is used without a guard (
{{#optional}},{{#if}}, or{{#with}}), the type-checker now throws an error at compile time instead of causing a runtime failure.Before: Runtime error -
"No values found for path '$['last']'"After: Compile-time error -
"Optional properties used without guards: last"Changes
.errorsproperty for structured accesstest/templates/bad/optional-noguard/Testing
All 26 TemplateMarkInterpreter tests pass. All 33 snapshots pass.
