+
+feat: parse merged-forward (chat history) messages (type 49, subtype 19)
+
+Previously, "Combine and Forward" messages only showed the title (e.g.
+"Chat History of Group X"). Now the agent extracts the full
+`<recorditem>` XML and renders each forwarded message as
+`sender: content`, giving agents visibility into the actual conversation.
+
+Closes #126
