webuiLibrePortalUpdate runs the per-app refresh hooks on every update (the
task processor fires it repeatedly), and gluetun's hook silently pulls a
~7MB servers.json from GitHub each time. The hook's stdout is captured by
`result=$($_hook)`, so on a slow link the update just sits with no output
right after "Generated apps-tools.json..." — it reads as a freeze.
- Throttle the fetch to once per CFG_GLUETUN_PROVIDERS_REFRESH_HOURS (24h
default; 0 = manual-only). Direct callers (Tools refresh, install hook)
pass GLUETUN_PROVIDERS_FORCE=1 to still get a guaranteed pull.
- curl --compressed (this JSON gzips ~7x) + --connect-timeout 15 so a slow
or dead link shrinks/fails fast instead of stalling every update.
- Print "Refreshing <app> WebUI data..." from the updater loop (outside the
output capture) so the step is visible instead of looking hung.
