Function debounceAsync

debounceAsync<T extends (...args: any[]) => Promise<any>>(
fn: T,
delay: number,
): { cancel(): void; (...args: Parameters<T>): Promise<ReturnType<T>> }
Creates a debounced version of an asynchronous function with cancellation support.

Only the last call within the specified delay is executed. All previous pending promises are rejected with a "Cancelled due to debounce" error.
Type Parameters
- T extends (...args: any[]) => Promise<any>
  Type of the async function to debounce.
Parameters
- fn: T
  The async function to debounce.
- delay: number
  Milliseconds to wait before executing the function.
Returns { cancel(): void; (...args: Parameters<T>): Promise<ReturnType<T>> }
Debounced async function with .cancel() method.
Example
```
const fetchData = async (q: string) => `Result for ${q}`;
const debouncedFetch = debounceAsync(fetchData, 300);

debouncedFetch("apple");
debouncedFetch("banana"); // cancels "apple"

await debouncedFetch("cherry");
// → "Result for cherry"
```
