// DDEDIT — edit the text content of a text-bearing entity in-place.
//
// Workflow:
//   1. Pick a text entity (or fire from double-click / a current selection).
//   2. The picked entity opens its in-place editor: a plain text box for
//      single-line text (Text, attributes, dimension override, tolerance) or
//      the rich MText editor for MText / MultiLeader. A Leader resolves to the
//      entity it annotates.
