Selection has no accessibility label of its own yet, so a logcat line at
begin/extend is the smallest way to confirm a real long-press-then-drag
reached DragArbiter/Selection on-device. Driven with the new ui-trace
holddrag action against iris-android-app's transcript screen: produced
"iris selection: begin at row ..." then a sequence of "... extend to row
..." lines, and a screenshot right after shows the expected highlighted
selection spanning multiple rows.
New `log = "0.4.28"` dependency (matching iris-android-app's own pin) --
transcript-ui had no logging facility before this.
