* fix(subagents): keep the subagent system prompt through context compaction

A subagent carries its whole system prompt (role, report contract, skills,
deferred tools) as the leading SystemMessage in state, because its agent is
built with system_prompt=None. Summarization only rescued tagged reminders and
the latest user message, so the first compaction summarized the prompt away
and every later model call in that subagent ran without its instructions.

Rescue system messages as well. The lead agent's prompt is not in state, and
its in-state SystemMessages are the tagged reminders already rescued, so the
lead chain is unchanged.
