### 🕗 Version & Regression Information

By trying out different versions in Playground, it looks like it works correctly in version 4.7.4 and lower

### 💻 Code

```ts
declare function call(fn: (a: string, b: T) => unknown): (b: T) => unknown;

declare function fn(
fn: (...args: Args) => unknown,
): (...args: Args) => unknown;

const result = call(fn(function (a, b: number) {}));
```

### 🙁 Actual behavior

The `a` parameter's type is `any`.

### 🙂 Expected behavior

The `a` paramater's type should be `string`

### Additional information about the issue

I encountered this while trying to create a helper function in a codebase that uses Effect:

```ts
import { Effect } from "effect"

function call(fn: (a: string, b: T) => Effect.Effect) {
return (b: T) => fn("value", b)
}

const fnA = call((a, b: number) => // a is `string`
Effect.gen(function* () {
return yield* Effect.succeed(`${a}: ${b}`)
}),
)

const fnB = call(
Effect.fn(function* (a, b: number) { // a is `any`?
return yield* Effect.succeed(`${a}: ${b}`)
}),
)
```

Start by running the linked TypeScript Playground example and compare the inferred types of `a` in the direct callback and the `fn`-wrapped callback. Investigate generic callback argument inference around `call` and `fn`; done means the wrapped callback infers `a` as `string` rather than `any`, while preserving the existing `b: number` inference.
