* refactor: make ElectronRendererClient::node_bindings_ a const ptr refactor: make ElectronRendererClient::electron_bindings_ a const ptr * fix: order-of-destruction bug in NodeService js_env_ depends on the uv_loop from node_bindings_, but is destroyed after node_bindings_ * chore: revert unintentional commit
