Extract shared functions from session.ts (toAgentPersistenceHandle,
buildStoredAgentPayload, ensureAgentLoaded) so both CLI/WebSocket
handlers and MCP tools use the same code paths for agent lookup.
Fix get_agent_status, get_agent_activity, and list_agents MCP tools
to fall back to persistent storage for archived agents. Add
includeArchived param to list_agents. Fix setupFinishNotification
to not wake archived callers. Delete dead agent-management-mcp.ts.
