The Linux DBus failure (org.freedesktop.DBus.Error.ServiceUnknown) arrives as an
unobserved AggregateException rethrown by the finalizer thread, so it is
temporally divorced from the mouse/keyboard gesture that made Avalonia issue the
DBus call (AT-SPI, portals, clipboard, IME). To pin the trigger, add an
ILSPY_LOG=DBUSDEBUG category: InputDiagnostics logs every pointer/key/focus event
into a rolling ring buffer, and the unobserved-task handler dumps that trail next
to the fully unwrapped exception. The unwrapper flattens the aggregate, walks
each inner chain, and reflects DBusException.ErrorName/ErrorMessage (Tmds.DBus is
a transitive dependency we can't reference directly) -- detail the bare
ToString() buries. The exception dialog and clipboard report carry the unwrapped
chain too, so the DBus error name shows even without the category enabled.
The assembly/analyzer panes now host SharpTreeView, but ~20 headless tests
still queried the old ProDataGrid surface (DataGrid/DataGridRow/Hierarchical
Model/HierarchicalNode), so they could not exercise the live tree. Retarget
them to SharpTreeView/SharpTreeViewItem and the flattener (ItemsSource) the
control actually exposes, and centralise the row/selection lookups in
TreeNodeAssertions so the scroll assertions ride the new container type.
Driving the retargeted tests against the real control surfaced four genuine
gaps, fixed here in SharpTreeView:
- Ctrl+A selected nothing on the first press because the base ListBox only
selects all once an item inside it is focused; handle it explicitly and make
the control itself focusable so the gesture works the moment the pane gains
focus.
- Left/Right navigation focused the parent/first-child container but never
moved the selection (selection must follow the caret); add SelectAndFocus.
- The expander toggle had no stable name; name it PART_Expander so hit-target
assertions can find it, and align the test to the shipped 13px column (kept
at 13 so the +/- box centres on the connector lines).
- Tree rows stretch to content width with horizontal scroll, so a row centre
can sit past the viewport's right edge; the pointer tests now click within
the visible grid width instead of the off-screen row centre.
The UseNestedNamespaceNodes re-bind test asserted a ProDataGrid Hierarchical
Model swap that no longer exists; rewrite it to assert the live flattener
reshapes the visible rows in place when the setting toggles.
Generalises the existing internal StartupLog into a public AppLog with
named categories. The Startup category (default-on) keeps the existing
[startup +Nms] format and Mark/Phase API, so all 44 call sites get a
mechanical StartupLog. -> AppLog. rename without behavioural change.

Adds BindTree_With_Small_AssemblyList_Settles_In_Reasonable_Time alongside
the existing 200-assembly [Explicit] benchmark. Not [Explicit] so it runs
in the regular suite; 8 copies of CoreLib with a 15s threshold catches
order-of-magnitude regressions in the open+settle pipeline without the
30s+ cost of the full benchmark.

Mirrors WPF's `ShowCFGContextMenuEntry` and `GraphVizGraph` utility behind
`#if DEBUG`. Right-click a `BlockContainer` reference in the IL output
("DEBUG -- Show CFG") → builds the ControlFlowGraph for the method, writes
a `.gv` file in the temp dir, shells out to `dot` (Graphviz) to render PNG,
opens the result with the OS default image viewer.

Replace LoadedAssembly's eager Task.Run(LoadAsync) with a Lazy<Task<LoadResult>> so
construction is free and the load only starts on the first GetLoadResultAsync /
await / .Result access. Active assembly's load fires from the saved-path restore
and runs without competition; everything else stays cold until either the user
expands a tree node OR the cooldown sweep fires.
