A run of 2+ consecutive edits to the same file now folds into one ClideHolderCard
labelled '# edits' (coalesceEditRuns, run after groupConversation) instead of a
stack of cards; a different file or an interleaving step splits the run. Every
edit stays reachable on expand.
The holder gained an optional aggregate status. New owned primitives: ClideSpinner
(the logo mark, monochrome, 3D Y-axis rotation, reduced-motion-aware) and
ClideStatusIndicator (running→spinner / success→check / error→cross, with an
AnimatedSwitcher seam for a richer transition later — kept self-contained, not
built on ConversationCard's mark). The activity card shares the same indicator.
