0.0.21

Fixed

• dusk:snap lists a merged control once. The walk printed every semantics node that carries an action, and MergeSemantics keeps each absorbed descendant in the tree as its own node flagged isMergedIntoParent, so a magic_starter MSSwitch row showed up as a button "X" [ref=e1] followed by a second button "X" [ref=e2] while the platform sees one node. A merged node is no longer printed and gets no ref; the walk still descends through it, and the line shape, the ref syntax and the textbox collapse are unchanged. Refs after a removed duplicate shift down by one each, so a script that hard-coded ref numbers has to re-snap. A WSelect that still prints twice is the wind side (two real platform nodes), fixed in fluttersdk_wind 1.9.3. (lib/src/extensions/ext_snapshot.dart)
