 * Sets up height synchronization between two side-by-side editors.

 * If one side is taller (due to word wrapping), inserts an invisible
 * padding widget on the shorter side to equalize the height.
 *
 * Maintains a persistent padding map so that paddings computed for
 * lines that later scroll out of view are preserved. On container
 * resize, performs a full reset since word-wrap changes invalidate
 * all previously measured heights.
