## Overview

```ts
class AnyToPromise<T = any> {
    status: AnyToPromiseStatus;
    constructor({ hasNextFunction }?: {
        hasNextFunction?: boolean;
    });
    get next(): (error?: any) => void;
    isDone(): boolean;
    call(cb: Function): Promise<AnyPromiseResult<T>>;
    reject(er: any): void;
    resolve(response?: any): void;
    destroy(): void;
    cancel(): any;
    done(status: AnyToPromiseStatus): void;
    handle(process: any, additionalProps?: {}): any;
    protected isCanceledResponse(process: any): boolean;
}
```

## Description

Utility that normalizes various async-like values (Promise, Observable, Stream, plain value)
into a single Promise-based flow with a consistent result shape.

This class is used internally to handle controller/middleware outputs, but can be
reused anywhere a unified async handling is desired.
