"""One-shot: napraw manifest.json dla istniejącego OTA update'u.

Bugs:
  1. Windows publish wpisywał `assets\<hash>` (os.sep) do URL'i.
  2. URL hosta ustawiony na 'goon-app.crawlbot.pl:8443' który nie ma DNS —
     mobile nie pobierze assetów. Właściwy host: api.goon-foss.org (port 443).

Normalizujemy `\` → `/` i podmieniamy hosta na CORRECT_HOST.
