Search archived Copilot chat sessions using Chronicle/session_store SQL as the first hint layer, then copilot-session-tools for targeted lookup/export. Use when the user says "search my chats", "find in chat history", "what did we discuss about X", "look up past sessions", "scan chats", "session history", "recent session where", "earlier conversation", "previous session", "that session where", or references a session-state path or session GUID. Also covers exporting narrowed sessions as markdown/HTML and launching the web viewer.
