Two reasons to pin a copy in the repo:
1. Users on networks where raw.githubusercontent.com is intermittent
can still get the deploy-ready file via a repo ZIP / clone.
2. The Apps Script relay protocol between mhrv-rs and Code.gs is
informal — upstream changes can silently break us. Keeping a
snapshot lets future-us diff against what we tested against
when diagnosing protocol-drift bugs.
Fetched verbatim from:
https://raw.githubusercontent.com/masterking32/MasterHttpRelayVPN/refs/heads/python_testing/apps_script/Code.gs
Credit stays with @masterking32. The assets/apps_script/README.md
next to it calls out that we don't modify this file — users deploy
it as-is into their own Google Apps Script project.
Updated the Setup Guide link in both the English and Persian
sections so offline / restricted-network users have a fallback path.
