Seed<TData> class sealed

Initial data to populate a query's cache before the first fetch.

Provide the data directly with Seed.value, or lazily with Seed.lazy when producing it is expensive (e.g. reading another query's cache).

A seed is applied only while the query has no data yet; data already in the cache is never overwritten by a seed.
