Auto-Aim / Look Ahead "wouldn't stay on": in the watch, current_menu is
still RUN_STAGE and hipDirectCompute declines on its !watch gate, so mouse
motion fell through to the legacy stick fallback (~3 counts/px/poll). A
~15 px flick crossed the watch's +/-0x2E threshold, which on a selected
option picks OFF/ON (game_option_toggle_input) and otherwise flips pages.
The mouse now contributes nothing while the watch is open or paused;
keyboard and pad drive the watch as before. Save/load round trip ruled out.
Build clean; bunker1 golden 3/3. Mouse feel-check owed (needs real motion).
