fix(es/helpers): Fix `_object_without_properties` crash on primitive values (#11571) **Description:** Fix `_object_without_properties` helper crash when destructuring primitive values with rest spread. When using object rest spread on a primitive value (e.g., `const { length, ...rest } = "hello"`), the transpiled code throws `TypeError: Reflect.ownKeys called on non-object`. **Root Cause** PR #11338 introduced `Reflect.ownKeys()` to avoid extra Proxy trap calls, but `Reflect.ownKeys` strictly requires an object argument per spec, unlike `Object.getOwnPropertyNames` which auto-boxes primitives. **Solution** Wrap `source` with `Object()` before calling `Reflect.ownKeys()` to auto-box primitives: ```javascript sourceKeys = Reflect.ownKeys(Object(source)); ``` This matches the ECMAScript [CopyDataProperties](https://tc39.es/ecma262/multipage/abstract-operations.html#sec-copydataproperties) behavior, where the internal `[[OwnPropertyKeys]]` method is called on the source after implicit object conversion. **Related issue:** - Closes #11570
