/**
 * Runtime binding for `states:ValidateStateMachineDefinition` — AWS's
 * static ASL validator (the Tier-4 check op for the Step Functions DSL).
 *
 * Service-scoped (no resource argument): validates any definition string
 * without creating or updating a state machine. `StateMachine`'s reconcile
 * runs this same check as a pre-flight; bind it in a function runtime to
 * validate definitions on demand (e.g. compiled `Sfn` programs before a
 * deployment pipeline applies them).
 * ### Validating Definitions
 * **Example:** Validate a definition string
 * ```typescript
 * const validate = yield* StepFunctions.ValidateStateMachineDefinition();
 *
 * const report = yield* validate({
 *   definition: JSON.stringify(definition),
 *   type: "EXPRESS",
 *   severity: "ERROR",
 * });
 * // report.result === "OK" | "FAIL"; report.diagnostics lists findings
 * ```
 *
