## 0.35.14

**`(fix):`** Fully qualify `Foundation.Data` in the generated HTTP client and test
templates. When an API defined a type named `Data`, the generated
top-level `Data` type shadowed `Foundation.Data` in those templates, so the
request-body builder and stub helpers resolved to the wrong type and failed
to compile. The remaining bare `Data` references now use `Foundation.Data`,
matching the convention already used elsewhere in the runtime.

**`(fix):`** Default an optional referenced request body to `nil` in the generated client
method, and omit the `request` argument from snippets and wire tests when an
example provides no body. Previously the parameter had no default value while
snippets emitted an empty initializer for the wrapped type, so endpoints with
an absent optional request body failed to compile.
