FindMyFiles.Highlighting.HighlightText - find-my-files

Attached behavior that renders SourceProperty into a TextBlock's Inlines, emphasizing the spans named by RangesProperty with bold + accent foreground. Lets the result list's name/path cells show match highlights without giving up their TextBlock styles, x:Phase, or virtualization: the same cell instance is reused across rows, and FindMyFiles.Highlighting.HighlightText.Rebuild(Microsoft.UI.Xaml.Controls.TextBlock,System.String,System.Collections.Generic.IReadOnlyList{FindMyFiles.Highlighting.HighlightRange}) clears and refills it on every change so a reused container never shows the previous row's text.
