Turn on #nullable enable across the AST consumer layer: the output visitor, the IL-to-C# builders (statement, call and expression builders, CSharpDecompiler, TypeSystemAstBuilder), the translation-result wrappers, the sequence-point and required-namespace collectors, and the annotation helpers. Optional inputs, fields and returns are typed nullable, detector out-parameters use [NotNullWhen(true)], and structurally-guaranteed dereferences use the null-forgiving operator. A few public parameters that already tolerate null are widened to match their downstream callers. The annotations emit no IL, so the Pretty suite stays byte-identical.
