Subject: [PATCH] Wiki sync: stop treating git's stderr as fatal

Mirror of github main + this script fix. PowerShell with
ErrorActionPreference=Stop was treating git's CRLF / 'remote: Processed N
references' stderr lines as script-fatal errors, aborting the sync
mid-flight. Switched to Continue + manual exit-code checks, drained stderr
on each git call, and disabled core.autocrlf in the throwaway clone.
