Re-review at 7286d320. Core.Scripting-017 (Medium, Security): System.Runtime.CompilerServices.Unsafe
added to ForbiddenFullTypeNames (Unsafe.As bypasses the type system without an unsafe context;
CWE-843 type-confusion into SetVirtualTag) + regression tests (rejects Unsafe.As, still allows
benign CompilerServices attributes). -018: refresh stale rejection message. Sandbox holds.
