Doc-comment folds were created with defaultCollapsed hardcoded to true, so /// blocks always started collapsed. The new Display option is bridged into DecompilerSettings like the other expand flags and drives the fold's default state. Detecting the last line of a doc-comment block requires sibling navigation between trivia nodes, so trivia now carry parent, sibling list, and index state. That state lives on the Trivia subclass to keep AstNode's size unchanged, and the tree API treats trivia as a separate navigation space: Next/PrevSibling and Remove work within the owning list, Slot is null, ReplaceWith throws instead of aliasing the trivia index into the parent's child slots, GetNextNode/GetPrevNode stop at the list boundary, Clone and CopyAnnotationsFrom deep-copy and reparent trivia, and CheckInvariant validates the trivia lists.
