Searching a package resolves its entries by file name against a case-insensitive
cache, which is right for an assembly reference but wrong for an archive entry:
two entries differing only in case are two files, and they collapsed onto one
LoadedAssembly, so one was searched twice and the other never. Keying the cache
by the entry itself separates them, and the entry's package-relative path
becomes the assembly's file name, which is what tells the copies of one assembly
in a multi-target package apart wherever a search result shows a location.
Cancellation was only checked between top-level list entries, so a walk the user
had already replaced by typing another character kept extracting package entries
alongside the run they were waiting for. The omnibar had no way to end its run at
all: its view model is per document tab and nothing cancelled it when the tab
went away.
