Why: On an empty workspace the primary button and the empty state both say to start by creating a task, but the action only toasted that a project was required.
Evidence: A fresh embedded instance returns an empty project list, so the first click never opened a conversation.
Impact: The first task now creates 「默认项目」 and opens it. Existing projects are unchanged.
