Restore PR #204's lazy normalize-only body. The upstream merge kept the eager switch+Configure block but routed writes through the lazy `Data` property, forcing `LazyData` materialization (and the DO_MAX_1000_COLUMNS guard) at construction time. Deferring layout to `LazyData` removes the eager 1000-column trip during query translation and obviates the `RecordSetHeader.Add` workaround. Made-with: Cursor

* Fix QueryTranslationException from RecordSetHeader.Join dead code Remove an unused `CreateTupleDescriptor(newColumns)` call in `RecordSetHeader.Join`. After upstream PR #248 changed the return statement to use the lazy two-arg `TupleDescriptor(a, b)` constructor, the local `newTupleDescriptor` became dead code. Combined with the later move of the >1000-column guard into `LazyData` (PR #204), this dead call eagerly tripped `NotSupportedException` during translation of complex queries whose transient joined headers exceed 1000 columns, even when the materialized recordset (after column pruning) would not. Made-with: Cursor * Bump DO version * Fix QueryTranslationException from RecordSetHeader.Add eager validation Switch `RecordSetHeader.CreateTupleDescriptor` (used by both `Add` overloads) from `TupleDescriptor.Create` to `TupleDescriptor.CreateFromNormalized`, matching the lazy normalization pattern already used by `Select` and the upstream-optimized `Join`. The eager `Create` factory routes to the single-arg `TupleDescriptor` constructor that synchronously materializes `LazyData` and trips the >1000-column guard during query translation, even when the resulting header is transient and gets pruned before execution. This affected `IncludeProvider`-driven translations of `Contains`-based predicates over already-wide intermediate headers (e.g. `e.statusesList.Contains(e.Membership.Status)` within complex multi-Select/SelectMany/GroupJoin chains). Add `Xtensive.Orm.Tests.Core/Rse/RecordSetHeaderTest.cs` with regression tests covering both `Add` overloads, `Join`, and the preserved runtime guard via `LazyData` access. Made-with: Cursor * Update DoVersionSuffix version * Fix SQL 2100-parameter limit in Bulk Update with large Contains Auto+TVP path of SqlDml.Variant lost its TvpTypeMapping because the complex-condition branch always allocated a fresh QueryParameterBinding, discarding the TVP binding the caller had just created. Reuse the incoming binding so CommandFactory can switch to a single table-valued parameter once the collection grows past MaxNumberOfConditions. Adds regression tests covering Bulk Update Contains over 2200 ids/guids. Made-with: Cursor * Fix botched merge of TupleDescriptor single-arg ctor in PR #481 Restore PR #204's lazy normalize-only body. The upstream merge kept the eager switch+Configure block but routed writes through the lazy `Data` property, forcing `LazyData` materialization (and the DO_MAX_1000_COLUMNS guard) at construction time. Deferring layout to `LazyData` removes the eager 1000-column trip during query translation and obviates the `RecordSetHeader.Add` workaround. Made-with: Cursor * Update DoVersionSuffix version
