What
Each transcript row now caches a narrowed view of the data it renders from, rebuilt only when a generation counter changes and a deep comparison shows something it depends on actually moved. A rendering-cost change with no visible surface.
Details
The cached view covers sibling tool-use ids, progress messages, hook counts, tool results and uses, and the sets of resolved and errored ids.
