fix(design): the saved-view chip on one line, one Escape per layer, the /watch action row (E28 S3d)

- SelectTrigger lays its toolbar value out as a row; the saved-view chip passes its glyph and
  modified dot through the icon/trailing slots (an <svg> is display:block and broke the chip in two).
- One Escape in a dialog's open list closed the list AND the dialog: the list's close flushes
  synchronously and pops its layer before the dialog's window listener runs. takeEscape() is the one
  close-on-Escape test (topmost AND not yet taken); Modal, the Welcome lightbox and useLayer use it,
  and keymap.dispatch ignores a taken Escape.
- /watch: the Download sits on the toolbar rung, level with the Repeat chip.
