…ntial types When CheckForCycles auto-enables PreserveReferences for a self-referential reference type, also set MaxDepth=64 (matching System.Text.Json/Newtonsoft.Json defaults) if no explicit limit is configured. This prevents a StackOverflowException DoS when mapping deeply nested distinct object graphs. Also fixes pre-existing .NET 9 build error in MultiThreadingIssues.cs where Array.Reverse() instance method (added in .NET 9, returns void) shadowed the LINQ Reverse() extension method.
