core/cli: prompt for a round's tool calls once

prompt_confirm_batch_async answers a ToolBatchConfirmHook with one box that numbers every call the round wants to make (continuation lines stay under their entry). The prompt is the plain ``Allow these N tool calls?`` confirm: a deny offers the same one comment for all of them, a non-interactive host denies, and the next round asks again.

The ReplState registry installs the hook next to the per-call one, and format_tool_confirm_box now shares the box drawing with the batch header.
