The registry serves no UI — that is maestro-web's job (connection-
orchestration spec §"UI hosting"). The rust-embed of web/dist was
legacy from NAP-218, before maestro-web was extracted (NAP-241), and it
made the registry (and thus the umbrella maestro binary) fail to compile
whenever web/dist was absent — e.g. a fresh cargo install --git after
the tracked .gitkeep was dropped. Remove web_assets.rs, the rust-embed
dep, and the / + /assets routes; the registry is now JSON/WS API only.
