RedWood.Core.Abstractions 5.0.299.1735

BREAKING: RedWood.Core.Abstractions.Media.IMediaInfoExtractor stays in this package, but its implementation and DI registration helper are no longer shipped (RedWood.Core.MediaHelper.Light was removed from the package set and has no replacement yet). Resolving IMediaInfoExtractor now requires the consumer to provide and register its own implementation. BREAKING: IDataProvider.QueryKeyless<T>() is a new interface member (reads keyless tables that do not implement IEntityBase, e.g. SQLite FTS5 virtual tables, on the provider's connection and active transaction, without IsDeleted filter; IEntityBase types are rejected); hand-written IDataProvider implementations must add it (mock proxies unaffected). IDataProvider.ExecuteInTransactionAsync contract is now rollback-only: an exception escaping a nested (joined) call prevents the outermost commit even if an outer caller catches it, and the outermost call rethrows that first inner exception. Earlier: ServiceValidationError structured fields (Code, Constraint, Limit, Actual, RecoveryHint) and ServiceException.ValidationErrorList.
