modules: extract fedserv-api leaf crate (protocol + service vocabulary)
Move NetEvent/NetAction/RegReply/Protocol and Sender/ServiceCtx into a dependency-free fedserv-api crate that a module builds against. Core keeps referring to them through re-export shims at crate::proto and crate::engine::service, so no consumer changes. Groundwork for external service and protocol modules.
