The Avalonia port gave DecompilationOptions a parameterless constructor
that silently defaults to new DecompilerSettings(). Several paths picked
it up and decompiled with default settings where the WPF version used
the user's current options: tree member filtering (CSharpLanguage.
ShowMember), PDB generation, the single-file / project / solution Save
Code paths, and the DEBUG decompile-all commands.
Promote the live-snapshot logic that was private to DecompilerTabPage-
Model (settings clone + Display-option bridge + toolbar language
version) to SettingsService.CreateEffectiveDecompilerSettings and use
it at every entry point. Remove the parameterless DecompilationOptions
constructor and make SolutionWriter require settings, so reaching for
defaults is an explicit choice rather than a silent fallback - that
default is exactly what masked these regressions. Search deliberately
keeps default settings (it only needs a type system to materialise).
