Running the TUI from XDG launchers (and some cron/ssh contexts) can leave HYPRLAND_INSTANCE_SIGNATURE unset. hyprctl then prints a plain-text error to stdout and exits 0, which made jq emit "Invalid numeric literal" to the terminal before the tui_err message. - ensure_hyprland_env: detect the running instance via `hyprctl instances` and export HIS before the first hyprctl call. - get_monitors: validate JSON with `jq -e` before parsing, fall back to text-mode `hyprctl monitors` if the JSON is broken. - pick_target: surface a clear error when HIS can't be recovered. - watcher: same recovery path so auto-pause still works when launched without HIS in env.
