Auto mode checks on subagents now see the parent session's verified human messages

Auto mode lets Claude Code decide on its own whether an action may go ahead, using a separate checking model called a classifier. A subagent is a helper Claude starts to work on part of a task, and a handoff passes work from one part of a session to another.

When the classifier checks a subagent step or a handoff, it is now given the turns from the parent session that are confirmed to come from a human, along with the earlier part of that conversation. Before, it was handed the parent's messages directly.
