The Export Project/Solution, Save Code and Compare tests decompiled whatever
the default assembly list seeds -- System.Linq, CoreLib, the Uri assembly --
so each spent ~10s purely on type count (Solution/CreateSolution/SaveCode/
DecompileAssembly ~10s, CompareView ~4.5s).
Add FixtureAssembly, which emits a minimal two-type assembly via
PersistedAssemblyBuilder, and point these tests at it. They still exercise the
full project/solution writer, save-to-file and compare-tree pipelines, but
each now runs well under a second (e.g. Solution_Mode 10.8s -> 0.3s,
CreateSolution 10.8s -> 0.2s, ShowIdentical 4.5s -> 0.3s).
