A row's own click_or_drag() selection handler always won the same gesture a list-level pan wanted, since run_sensors gives the inner layer first refusal every frame it's pressed. DragArbiter (iris/src/sense.rs) decides pan vs. select the way Android does: vertical drag pans immediately, a held stationary press starts a selection after LONG_PRESS, and a horizontal drag on already-selected text extends immediately. transcript-ui's Selection::drag routes every row's drag through one arbiter per list, driving List::scroll for a pan instead of a second scroll mechanism. 8 new unit tests (iris::sense::drag_arbiter_tests); cargo fmt/clippy/test --workspace and cargo ndk (iris, transcript-ui) all clean; run-headless.sh screenshot byte-identical to before the change.
