[7.7.9, local tarball] UI still 30 % English – community zh-CN translation entry removed?

Hi maintainers,

UPDATE after deeper digging (still on 7.7.9 manual install, Node 22.14.0, Yarn 1.22.22, Deno 2.5.2, Ubuntu 22.04):

1. What I already tried

   • Set “Server Default” and personal language to zh-CN → restarted Rocket.Chat and browsers.
   • Grepped the whole bundle for zh-CN.i18n.json → only moment/locale/zh-cn.js exists; no Rocket.Chat language file.
   • Checked Admin → Languages: still only “English” is listed.
   • Looked for the old “Import Translations” button mentioned in 6.x docs → UI element is gone.
   • Crowdin project shows 100 % zh-CN translated, but no “Download” button visible for non-maintainers.

2. Suspicion
   It looks like the community-translation import UI was removed in 7.x. If that is intentional, could you clarify:

   a) Are language packs now shipped only inside releases?
   b) If so, why is zh-CN not packaged although it is 100 % translated?
   c) Is there a CLI workaround (meteor or yarn transifex) to inject the file manually?

3. Request
   Please confirm whether the entry point was deliberately dropped or just relocated.
   A short “known issue / will ship in 7.8” or “copy file X to folder Y” would save a lot of guessing.

Happy to test any nightly build or PR. Thanks for your hard work!

No source file or test is named. Start by tracing how the 7.7.9 release packages language files and how Admin → Languages discovers them, then compare that path with the Crowdin zh-CN output. Done means documenting the supported import or packaging path and confirming whether zh-CN is intentionally excluded.
