## Summary
Fixes an issue where the AI chat would show loading shimmers
indefinitely when opened on a workspace with no conversation history.
**Root cause:** The `isLoading` state in `useAgentChat` included
`!currentAIChatThread`. On workspaces with no chat threads,
`currentAIChatThread` remained `null`, causing `isLoading` to be
permanently `true`.
**Changes:**
- Remove `!currentAIChatThread` from `isLoading` calculation in
`useAgentChat` - this state should only reflect streaming/file selection
status
- Auto-create a chat thread in `useAgentChatData` when the threads query
returns empty, ensuring a valid thread exists for the `useChat` hook to
initialize properly
- Add primary font color to empty state title for better visibility
## Test plan
1. Create a new workspace or use a workspace with no AI chat history
2. Open the AI chat
3. Verify the empty state shows (not infinite loading shimmer)
4. Send a message and verify it works correctly
