Inline `messageView` and `labels` objects passed to CopilotChat caused all completed assistant messages to re-render on every keystroke because: 1. `ts-deepmerge.merge()` deep-clones its inputs, producing a new `messageView` reference on every render even when content is identical — defeating `MemoizedSlotWrapper`'s shallow equality check. 2. An inline `labels` object (new reference each render) invalidated the `mergedLabels` useMemo in `CopilotChatConfigurationProvider`, causing every `useCopilotChatConfiguration()` consumer to re-render on every keystroke. 3. The inline `onAddFile` arrow function was a new reference each render. Fixes: - Replace `merge()` with shallow spread; stabilize `messageView` via a ref + `shallowEqual` guard so the same object reference is returned when props are shallowly equal across renders. - Use `useCallback` for `handleAddFile`. - Add JSON.stringify-based dep keys in `CopilotChatConfigurationProvider` so `mergedLabels` is only recomputed when label values actually change. Adds deterministic render-count regression tests (FOR-75) that fail on the unfixed code and pass after the fix. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
