Silence jq noise when the reload guard probes dead Hyprland instances

hyprctl prints "Couldn't connect ..." on stdout for stale instance dirs
left in /run/user/*/hypr/, so jq's parse error leaked into pacman's
pre-transaction hook output. The dead instances were already skipped
correctly; only the stderr noise escaped.
