bump: patch type: fix A dispatched action no longer allocates a record each time. dispatch A { ... } made a fresh record for the queue, and Ludic frees nothing, so a system dispatching every frame (an input's Move, a frame's time) grew the program by a record a frame. The queue now keeps a list per action: a dispatch takes the next one (making one only when all are queued), fills every field as new would - given, or its default - and drain_actions() hands them all back once the queue is empty. A reducer reads its action only during the drain, so nothing sees a record after it is reused; keep what must last in the state, not the action. ludic.base's actions_test holds a reused record getting its defaults back.
