Test cancellation at both workspace-resume entry points.

When prepareHistoryItemForResume returns undefined, neither entry point may restore or reveal the task. Add separate caller-level tests:

  • ClineProvider.showTaskWithId: assert that createTaskWithHistoryItem and the chatButtonClicked action are not called.
  • api.resumeTask: assert that createTaskWithHistoryItem is not called.

The existing helper tests cover preparation cancellation only. They do not exercise either caller's early-return behavior.
