fix(compact): place destination reminder at end of compaction summary

Tell the compactor to include the <message to="name"> wrapping reminder
verbatim at the END of the summary so it's the last thing the agent sees
after compaction. Previously the instruction just asked to "preserve"
routing info, which the compactor could place anywhere or summarize away.
