- Added optional snapcompact savings calculation in context breakdown with caller opt-in and setting gate. - Added /context command integration to surface snapcompact savings and related skip reasons. - Added context report sections for vision capability, tool-result imaging counts, and next-request token totals. - Added shared inline-swap planning/savings estimation and transformer use for planned frame swaps.
