The Display-options "Expand using declarations / member definitions after decompilation" checkboxes had no effect: the live decompile cloned DecompilerSettings and baked in the language version but never copied these two flags from DisplaySettings. TextTokenWriter reads settings.ExpandUsingDeclarations / ExpandMemberDefinitions to decide each fold's DefaultClosed, so without the bridge both defaulted false and every using / member fold came back collapsed regardless of the setting.
This fixture was missed by both the helper-extraction and visual-breakpoint
sweeps, so it still carried 16 copies of the boot prologue and no captures.
Route it through TestHarness.BootAsync / TreeNavigation and add a Step after
each decompile, matching every other headless fixture.

WPF's CSharpLanguage doesn't override DecompileNamespace -- clicking
a namespace falls through to the base Language.DecompileNamespace,
which writes just the namespace name as a `// Foo.Bar` comment.
The avalonia port's override decompiled every top-level type in the
namespace, which on a large assembly turned a single click into a
multi-second blocking decompile of hundreds of types.
Remove the override so clicking a namespace lands the same cheap
comment-only output the WPF app shows. Users who do want the full
namespace decompiled can still get it via right-click > Save Code,
which routes through a separate path that constructs the project
explicitly.
ILLanguage's override is intentionally preserved -- IL mode in WPF
does disassemble the namespace; we match that.

Ctrl+M toggles the innermost fold containing the caret. Ctrl+Shift+M collapses
all when any fold is open and expands all otherwise (parity-based toggle).

Tree-node selection now updates the inner Content of one persistent
ContentTabPage instead of swapping the dockable in the dock. The
wrapper view (ContentTabPageView) keeps both inner views — the
decompiler text editor and the metadata grid — pre-realised in the
visual tree from construction time and toggles which is visible based
on Content's runtime type.

Replaces the brittle root.GetVisualDescendants().OfType<T>().Single() / .First()
pattern with a new WaitForComponent<T>() extension that polls until the requested
control is in the visual tree, then returns it. Avalonia.Headless tests routinely
queried the visual tree before lazily-templated panes (DataGrid, dock content)
had materialised, surfacing as intermittent 'Sequence contains no elements'
failures across the suite.

Each tree-expansion, selection change, command execution, async wait and
key/mouse injection inside an [AvaloniaTest] now carries a short imperative
comment on the line above (e.g. "// expand typeNode", "// select methodA",
"// wait for assemblies to load", "// execute aboutCmd"). The comments are
the same scaffolding the manual debug-with-screenshot workflow uses to
follow what's happening at each breakpoint, surfaced into the committed
source so the tests are readable without the breakpoint markers attached.

Adds a leading paragraph describing what each test verifies and Arrange /
Act / Assert markers (split into numbered phases for multi-step tests) so
the intent of each fixture is readable from comments alone.

XML / XSD / XSLT / XAML resources don't go through the C# decompiler so the
DecompilerTabPageModel has no pre-collected foldings — only HighlightingService
was kicking in. Run AvaloniaEdit's bundled XmlFoldingStrategy when the active
syntax extension is .xml so multi-line elements collapse from the gutter.
