- find_draggable_at: break instead of return None on non-top non-tableau
hit so remaining pile searches are not abandoned early (M-9)
- update_stock_count_badge: run only when GameStateResource changes (M-5)
- update_drop_highlights: run only when DragState changes (M-6)
- update_high_contrast_borders/backgrounds: run only when SettingsResource
changes (M-7)
- update_selection_hud: run only when SelectionState or GameStateResource
changes; uses resource_exists_and_changed to avoid panic in tests where
SelectionState is not registered (M-8)
- Volume toast threshold: f32::EPSILON → 0.001 to avoid spurious toasts
from float rounding noise in settings events (M-10)
- check_no_moves: collapse read().next().is_some() + clear() into a single
read().count() > 0 drain (M-11)
