chore(deps): bump mdns-sd from 0.11.5 to 0.19.1 in /src-tauri

Bumped only for src-tauri's qconnect-discovery path. qbz-cast (chromecast/
DLNA) stays on 0.11 because mdns-sd 0.19 changed the address API
(HashSet<IpAddr> → HashSet<ScopedIp>) and adapting qbz-cast is real
work outside dependabot scope. Workspace now carries both versions
in the graph; both compile and operate independently.
