[ nostr-dev-kit/ndk ] fix(cache): skip cache queries for subscriptions with only ephemeral kinds Ephemeral events (kinds 20000-29999) are never stored in cache, so querying the cache for them is wasteful. This adds proper filtering to skip cache queries when all filters contain only ephemeral kinds. Also exports filterForCache utilities for cache adapters to use.
