Drop the appWebuiRefresh_gluetun -> webuiGenerateGluetunProviders wrapper; rename the function itself to appWebuiRefresh_gluetun and point the installer + the gluetun_refresh_providers tool at it. One name, no indirection. Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com> Signed-off-by: librelad <librelad@digitalangels.vip>
