The .NET SDK now supports an optional per-operation `Serializer` (an ILambdaSerializer) on StepConfig, CallbackConfig, InvokeConfig, WaitForConditionConfig<TState>, and ChildContextConfig; when null the globally-registered serializer is used. Update the C# tabs on the serialization page (Default serialization, SerDes interface, StepConfig, CallbackConfig) and the StepConfigExample/CallbackConfigExample examples. Map/Parallel C# tabs left as-is pending two-level (item + whole-result) support.
MapConfig<TItem> and ParallelConfig now expose ItemSerializer for each item/branch result; the aggregated batch envelope is SDK-internal and not user-serialized (no whole-result serializer). Update the Map/Parallel C# tab and MapConfigExample.

Summary
Documents the .NET per-operation serializer override on the C# tabs of the serialization reference. Companion to aws/aws-lambda-dotnet#2555.
SerializeronStepConfig/CallbackConfig(and note it reusesILambdaSerializer, so no new SerDes interface), and theItemSerializeronMapConfig/ParallelConfigfor per-item/branch results (the aggregate batch envelope is SDK-internal, so there is no whole-result serializer).Notes
Docs-only. Pairs with the SDK feature PR aws/aws-lambda-dotnet#2555.
