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.
