Function withRetry

withRetry(
    run: (attempt: number) => Promise<T | null>,
    options?: RetryOptions & {
        onRetry?: (attempt: number, attempts: number, delayMS: number) => void;
    },
): Promise<T | null>
Runs an operation until it produces a result, backing off between tries.

run signals failure by resolving null rather than throwing — the socials helpers log the API's message and resolve null, so a loop that only caught exceptions would never retry.
Parameters
- run: (attempt: number) => Promise<T | null>
  Receives the 1-based attempt number; resolve null to retry.
- options: RetryOptions & {
  onRetry?: (attempt: number, attempts: number, delayMS: number) => void;
  } = {}
  RetryOptions, plus onRetry for logging before each delay.
Returns Promise<T | null>
The first non-null result, or null once every attempt is spent.
Example
```
import { withRetry } from "naystack/socials";

const id = await withRetry(() => createContainer(token, params), {
  attempts: 3,
  onRetry: (attempt, attempts, delayMS) =>
    console.warn(`attempt ${attempt}/${attempts} failed — retrying in ${delayMS}ms`),
});
```
