  Persists extracted retrievable text bytes into consumer storage and returns a
  {@link @nhtio/adk!SpoolReader} (LLM execution context variant). The handler
  wraps the reader in a {@link @nhtio/adk!SpooledArtifact} for `new
  Retrievable({ content })` and persists the record via `storeRetrievable`
  separately. Returns a value; does NOT touch the turn Sets.

# Type Alias: DispatchRetrievableBytesStoreFn

```ts
type DispatchRetrievableBytesStoreFn = (
  ctx: DispatchContext,
  id: string,
  bytes: ConduitBytes,
) => SpoolReader | Promise<SpoolReader>;
```
