## Summary Adds a new `diff_status_change` event kind to the `/chats/watch` pubsub stream so the sidebar can update diff status (PR created, files changed, branch info) without a full page reload. ### Problem When a chat's diff status changes (e.g. PR created via GitHub, git branch pushed), the sidebar didn't update because: 1. The backend `publishChatPubsubEvent` didn't include diff status data 2. The frontend watch handler only merged `status`, `title`, and `updated_at` from events ### Solution A **notify-only** approach: a new `ChatEventKindDiffStatusChange` event kind tells the frontend "diff status changed for chat X" — the frontend then invalidates the relevant React Query cache entries to re-fetch. ### Backend changes - **`coderd/pubsub/chatevent.go`**: New `ChatEventKindDiffStatusChange = "diff_status_change"` constant - **`coderd/chatd/chatd.go`**: New `PublishDiffStatusChange(ctx, chatID)` method on `Server` - **`coderd/chats.go`**: New `publishChatDiffStatusEvent` helper. Published from: - `refreshWorkspaceChatDiffStatuses` — after each chat's diff status is refreshed via GitHub API - `storeChatGitRef` — after persisting git branch/origin info from workspace agent ### Frontend changes - **`AgentsPage.tsx`**: Handle `diff_status_change` event by invalidating `chatDiffStatusKey` and `chatDiffContentsKey` queries - **`ChatContext.ts`**: Remove redundant diff status invalidation that fired on every chat status change (the new event kind handles this properly)
