auto-claude: subtask-1-1 - Add useTaskStore import and update task state after successful PR creation (#1683)

- Added useTaskStore import from stores/task-store
- Added task state update logic in handleCreatePRs after successful PR creation
- Tasks now transition from human_review to done status when PR is created
- Task metadata is updated with prUrl from successful PR result
- Only updates tasks that had successful PR creation (not skipped, error, or alreadyExists)
- Follows exact pattern from TaskDetailModal.tsx for consistency
