This reverts commit 63ebab5.
- Performance tests of constructors - ToString test for ConcatTransform
- everywhere inside the project transformations are perforemed on valid descriptors so we can skip checks of structs, transformations are public though so we have to keep validation in public ctor

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
