Ratify the edition split and the 2026-07-28 design-review resolutions

Edition split follow-through: 12-editions.md and 13-native-undo.md join the
corpus; git-era docs (06, 07) are Pro-scoped and cross-references realigned.

Resolution session rulings written in place: caret chords yield to any focused
text control (04, 11); the drop settle holds its proposal as overlay state and
02 gains the overlays family; Duplicate gets the save-panel fallback and a
cancellable copy walk (03); Finder open is a standard document open (02);
failed first opens record before loading with the folder name provisional (02);
trash pointer ranges skip by kind, full-height marquee surface, Select All by
kind, rows-only trashed universe (02, 04); Empty Trash counts entries (03);
create handoff reads as one arrival (02); range-anchor lifecycle, board-
background click grammar, jump landing cards, lane-domain shift-arrows (04);
Reduce Motion restated per voice (10).
