 * Wire-format contract for the email add-on: the email a model drafts and the
 * result of dispatching it. Pure (zod + inferred types, no Node-only imports)
 * so the server-side sender, the Mastra tool, and the React approval UI all
 * validate / type against one definition.
 *
 * Array fields intentionally avoid `.min()` / `.nonempty()`: those emit
 * `minItems` in the JSON schema, which some Model Serving endpoints reject
 * ("array types do not support minItems") when the schema is forwarded as a
 * tool definition.
