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.

User-reported: editor hover tooltips were not wide enough to show full
method signatures. Root cause was a three-way layout interaction —
DocumentationRenderer.AddSignatureBlock created the signature
SelectableTextBlock with TextWrapping.NoWrap, the outer Border capped
MaxWidth at 600px, and the wrapping ScrollViewer disabled horizontal
scrolling. So anything past 600px was simply clipped, with no way to
reveal the rest.

The three editor-command tests (Copy_Entry_Reflects, Copy_Execute, SelectAll_Execute)
selected `System.Linq.Enumerable` (the whole type, 300+ LINQ methods) and waited
on `view.Editor.Document.TextLength > 0` — a 15s `WaitForAsync` poll. In suite
context this was sloppy: it could latch on stale editor content from a previous
test, and in isolation it occasionally raced past 15s on a slow system,
producing the intermittent `failed: 1` we saw earlier.

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).

Mirrors WPF's ZoomScrollViewer behaviour without templating AvaloniaEdit's
TextEditor. The Avalonia path scales the editor's FontSize (which feeds
DisplaySettings.SelectedFontSize) on Ctrl+Wheel; AvaloniaEdit lays out at the
new size on the next render. WPF's full-content-tree LayoutTransform approach
doesn't fit AvaloniaEdit's architecture, but the font-scale result is what
users actually expect from "editor zoom".

Foldings persistence rounds out the view-state work that landed in 185e0551d
(caret + scroll). Mirrors WPF's DecompilerTextViewState.SaveFoldingsState /
RestoreFoldings semantics verbatim — including the layout-checksum gate that
refuses restoration when the new document's foldings don't match the captured
layout, so a stale snapshot can't accidentally expand random regions of a
shifted document.

Promotes the modern .NET XML-doc lookup from the Avalonia port into the
shared ICSharpCode.Decompiler library so every host (WPF, Avalonia, any
third-party consumer of XmlDocLoader) gets hover/tooltip documentation
for system entities without per-host fallback wiring.
The decompiler-view hover tooltip's XML-documentation lookup goes through
the shared ICSharpCode.Decompiler.Documentation.XmlDocLoader. That helper
only knows two layouts: .xml beside the .dll, and the .NET Framework
reference-assemblies paths (Program Files (x86)\Reference Assemblies\
Microsoft\Framework\v1.0 … v4.8.1). Modern .NET runtime DLLs
(System.Private.CoreLib.dll, System.Linq.dll, …) ship without any .xml
beside them — the XML files live in the parallel reference pack at
The Reload/Remove/SearchMSDN/OpenContainingFolder/DecompileInNewView
tests used to call `entry.Execute(synthetic TextViewContext)` against
a hand-built context. They now select via the assembly-tree model,
build the context menu through `BuildContextMenuForCurrentState`
(the same call the live `Opening` event makes), and fire the menu
item's `Click` routed event — the same handler the user's click
invokes. This widens the coverage to the menu-build → click-handler
attachment pipeline.

Mirrors WPF's TextView/EditorCommands.cs: CopyContextMenuEntry and
SelectAllContextMenuEntry are [ExportContextMenuEntry] MEF exports
gated by TextViewContext.TextView, with Category=Editor and low Order
so they appear at the top of the editor right-click menu. The
hand-rolled MenuItem fallback in DecompilerTextView.OnContextMenuOpening
is removed — the MEF entries replace it.

CaretHighlightAdorner is an IBackgroundRenderer on KnownLayer.Caret with a
hand-rolled animation curve (Stopwatch + DispatcherTimer at ~60fps invalidating
the layer) instead of WPF's RectAnimation/BeginAnimation, since AvaloniaEdit
has no XAML-style animation primitive for ad-hoc visuals. Same timing as WPF
(300ms grow, 300ms shrink, opacity fade 450-650ms, 1s lifetime).

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.
