The startup welcome page renders the same About content in the reusable main tab. Help > About opened a second, static About tab beside it, so the user saw the page twice. Track the welcome content and, while it is still the live main-tab content, have Help > About activate it rather than open the singleton. Falls through to the singleton once a tree-node selection has replaced the welcome page.

Two first-run behaviours that the previous version had and the port had
lost. When a launch has nothing to restore (no saved tree path, no
command-line target), greet the user with the About page in the main
tab instead of an empty "(no selection)" view; the greeting is fired
after the tree is ready and only takes the main tab when it's still
empty and active, so it can't steal activation from a tab the user
opened meanwhile (e.g. Compare...). And seed the default list with the
.NET framework ILSpy itself runs on - every managed assembly in the
running runtime's shared-framework directory. Headless tests opt out of
that seed (re-opening ~150 assemblies per test is ~10x slower) and fall
back to the minimal trio, leaving their expectations unchanged.

SearchPaneModel gains an Activate(SearchResult) method that resolves
result.Reference through AssemblyTreeModel.FindTreeNode and moves the
assembly-tree selection there — exactly the WPF NavigateToReferenceEventArgs
flow, minus the message-bus indirection. SearchPane.axaml.cs wires
DoubleTapped + Enter on the results ListBox to call Activate.
