Widen CacheValueSerializer.serialize and .deserialize return types from sync-only to string | Promise<string> and CacheHandlerValue | null | Promise<CacheHandlerValue | null> respectively, and add await at both call sites in redis-strings.ts. This allows users to replace blocking sync codecs (e.g. brotliCompressSync) with non-blocking async variants (e.g. brotliCompress) without blocking the Node.js event loop under load. Existing sync implementations continue to work unchanged — await on a non-Promise is a no-op in JavaScript.
