Ty Smith c32d695cd9 macos: stop corrupting modifier state in repeat-task cleanup
spawn_repeat_task() takes a Mac CGKeyCode, but the cleanup block was
passing that value to update_modifiers(), which expects a Linux evdev
scancode (it calls scancode::Linux::try_from(key)). The two codespaces
collide on several values, so cancelling the repeat task could
silently clear a still-held modifier:

  Mac LeftShift   = 56  == Linux KeyLeftAlt   = 56  -> clears Mod1Mask
  Mac Down arrow  = 125 == Linux KeyLeftMeta  = 125 -> clears Mod4Mask
  Mac Up arrow    = 126 == Linux KeyRightMeta = 126 -> clears Mod4Mask
  Mac Backslash   = 42  == Linux KeyLeftShift = 42  -> clears ShiftMask
  Mac "9"         = 29  == Linux KeyLeftCtrl  = 29  -> clears ControlMask

In practice this broke chords such as Shift+Option+X and Cmd+Down:
pressing Shift while holding Option cancels Option's repeat task and
runs the buggy cleanup, which then interprets Mac LeftShift's code
(56) as Linux KeyLeftAlt and removes Option from the modifier state.
The next key arrives with Shift only, so window-manager bindings on
the original Option chord never fire.

Remove the buggy update_modifiers() call. Modifier state is owned by
the main consume() loop, which already calls update_modifiers() with
the correct Linux scancode on the real release event.
