PR Summary

Low Risk
Scoped UI state/cache changes to Copilot chat selection; minimal blast radius, with main risk being incorrect list ordering or stale cache behavior.

Overview
Fixes a race in the Copilot panel where creating a new chat could immediately be de-selected because the selected chatId wasn’t yet present in the cached chat list.

The auto-select effect now waits for a non-empty list before selecting a default chat, and handleCopilotNewChat now seeds the new chat into the React Query cache (copilotChatsKeys.list(workflowId)) before setting copilotChatId, then triggers a refetch to reconcile.

Greptile Summary

This PR correctly addresses two interlinked bugs in the copilot panel. Bug 1: autoSelectAttemptedForRef was marked before the empty-list check, so a workflow with an initially empty list would never auto-select once chats loaded. The fix moves the length === 0 guard before the ref mutation. Bug 2: newly created chats were immediately deselected because the auto-select effect saw a stale list and cleared copilotChatId. The fix optimistically seeds the new chat into the React Query cache via queryClient.setQueryData before calling setCopilotChatId, so the effect finds the chat in the list and leaves it selected.

Confidence Score: 5/5

Safe to merge — targeted, well-reasoned fixes with no regressions introduced.

Both changes are minimal and correct: the auto-select guard reordering is straightforwardly sound, and the optimistic cache seed matches the exact CopilotChatListItem shape. No new state is introduced and the subsequent invalidateQueries reconciles the cache with the server. No P0 or P1 findings.

No files require special attention.
