UDS listen already worked for proxying (the listen string is passed to xray verbatim and port 0 is accepted), and the Go sub/link layer already ignores the bind listen. The only gap was the frontend resolveAddr, which would put a socket-path listen into share/sub links (e.g. vless://uuid@/run/xray/x.sock:0). resolveAddr now treats a path-style listen (starting with / or @) as having no client-reachable address and falls back to hostOverride/hostname. Adds a test and a Listen-field help hint across all locales.
