Function createCacheService

createCacheService(options: CacheServiceOptions): ServiceHandler
Create a cache service that wraps an existing cache implementation as a ServiceHandler.

Cache relay.subscribe subscriptions are one-shot — they query, deliver results, send EOSE, and are done. No long-lived subscription tracking needed. Cache query failures are best-effort: EOSE is sent even on failure.
Parameters
- options: CacheServiceOptions
  Cache implementation to wrap
Returns ServiceHandler
A ServiceHandler ready for runtime.registerService('cache', handler)
Example
```
import { createCacheService } from '@kehto/services';

const cache = createCacheService({
  query: (f) => workerRelay.query(f),
  store: (e) => workerRelay.store(e),
  isAvailable: () => workerRelay.ready,
});
runtime.registerService('cache', cache);
```
