* fix(proxy): confirm runtime chain updates before UI changes

* fix(clipboard): propagate proxy environment copy failures

* refactor(dns): remove ignored runtime patch

* refactor(core): trim unused upgrade response fields

* refactor(ipc): avoid redundant response copies

* refactor(proxy): clarify automatic proxy query naming

* chore(tests): remove added IPC regression tests

* refactor(ipc): enforce typed command boundaries

* chore(contract): check generated bindings before push

* refactor(ipc): remove unused proxy liveness payloads
