A function that determines how a settings store entry should be scoped.
Returns a string that will be used as the scope key for storage isolation.

*Example*

```ts
// User-specific scoping
const userScope: SettingsStoreScopeFunction = ({ ctx }) => ctx.activeUserId || '';

// Channel-specific scoping
const channelScope: SettingsStoreScopeFunction = ({ ctx }) => ctx.channelId || '';

// User and channel scoping
const userAndChannelScope: SettingsStoreScopeFunction = ({ ctx }) =>
  `${ctx.activeUserId || ''}:${ctx.channelId || ''}`;
```

```ts title="Signature"
type SettingsStoreScopeFunction = (params: {
    key: string;
    value?: any;
    ctx: RequestContext;
}) => string
```
