Keep SizeMode.Exact: Single and Responsive never reflow on resize (#214)

GlanceAppWidget.resize returns early for both, so the grid was never recomposed
for a new size and a resized widget clipped instead of reflowing. Exact costs one
serialised copy per host size, which the view cuts have made affordable again.

Drops the options-derived width that went with Single; LocalSize is exact here.
