Subject: [PATCH] fix(steamcmd): ensure core HL1 files are present after appid
 90 update

* Added checks to verify the presence of core HL1 files after updating appid 90.
* If files are missing, an update is forced and errors are logged.
* Exits the script if files are still missing after the retry.
