### 🕗 Version & Regression Information

This bug appears to occur as far back as TS 3.3 up to the current nightly build, as tested in the Playground.

### 💻 Code

```ts
type Arr = Array | [] | [string];

declare const arr: Arr;

const [a] = arr;
a.toString(); // Expected: error. Actual: no error. ❌

const b = arr[0];
b.toString(); // Expected: error. Actual: error. ✅
```

`.d.ts` from Playground:
```ts
type Arr = Array | [] | [string];
declare const arr: Arr;
declare const a: string | number | undefined;
declare const b: string | number | undefined;
```

### 🙁 Actual behavior

When destructuring a value whose type is an array, an empty tuple, and a non-empty tuple, the destructured value isn't flagged as possibly `undefined` which caused a runtime error. The value is correctly flagged as possibly `undefined` when accessing it by index.

### 🙂 Expected behavior

When destructuring a value whose type is an array, an empty tuple, and a non-empty tuple, the destructured value should be flagged as potentially being `undefined`.

### Additional information about the issue

This seems related to #55661 except, in this case, the union contains a mix of tuples and an array.

Start with the linked TypeScript Playground reproduction and compare the inferred type for tuple destructuring with the indexed-access result. Review the related issue #55661 for context. Done means the destructured value is reported as potentially undefined in this mixed array-and-tuple union case without changing the correct indexed-access behavior.
