Detailed Description

Tests for automatic line-wrapping inside EditorCells.

A soft (word-wrap) line break is derived layout data kept OUTSIDE the content string, in the EditorCell::GetSoftBreaks() side table (a hard break is a '
' character in the content). StyleText() re-derives the whole table on every restyle, so wrapping is a pure function of (content, width) that must never change the cell's content or leak into serialization, the clipboard or the selection string. Each break offset is the start of a continuation display line. These tests pin that for the prose path, the code path, and the operator-aware code breaks (wrap after + - * / ( ) ; $, but never inside a '**').

Windowless: real GroupCell/EditorCell against a memory-DC Configuration, no Worksheet, no wxFrame - the test_WorksheetLayout pattern.
