Matt Hill 6c72a22178 SDK beta.62: fix dynamicSelect crash on empty values, add smtpShape
- Guard z.union() against empty arrays in dynamicSelect/dynamicMultiselect
  by falling back to z.string() (fixes zod v4 _zod TypeError)
- Add smtpShape: typed zod schema for store file models, replacing
  smtpInputSpec.validator which caused cross-zod-instance errors
- Bump version to 0.4.0-beta.62
