// # CocoonServiceImpl - thin-wrapper dispatcher
//
// Domain files hold all typed RPC implementations. This module keeps:
// - CocoonServiceImpl struct + helper methods
// - process_mountain_request (legacy generic router, ~600 lines)
// - send_mountain_notification (push dispatcher, ~400 lines)
// - One-line delegates for all 78 typed RPCs
