Namespace Terminal.Gui.Editor.Document.Utils
Shared utility types used by the document layer — Rope, Deque, CompressingTreeList, FileReader, and text helpers.
Includes the Rope<T> data structure (a balanced B-tree for efficient insert/delete in large sequences), Deque<T> (double-ended queue), CompressingTreeList<T> (run-length compressed list), FileReader (encoding-detecting file reader), IFreezable (immutability pattern), and various string/text helpers.
These types are adapted from AvaloniaEdit's utility layer and have no dependency on Terminal.Gui.
