fix(db): use Ref<T, Nullable> brand instead of Ref<T> | undefined for nullable join refs in declarative select (#1262)
The declarative select() callback receives proxy objects that record property accesses. These proxies are always truthy at build time, but nullable join sides (left/right/full) were typed as Ref<T> | undefined, misleading users into using ?. and ?? operators that have no effect at runtime. Nullable join refs are now typed as Ref<T, true>, which allows direct property access without optional chaining while correctly producing T | undefined in the result type.
Fix unbounded WHERE expression growth in DeduplicatedLoadSubset when loading all data after accumulating specific predicates. The deduplication layer now correctly tracks the original request predicate (e.g., where: undefined for "load all") instead of the optimized difference query sent to the backend, ensuring hasLoadedAllData is properly set and subsequent requests are deduplicated.
