fix: stash generated files before pull in visitor counter workflow

Visitor counter script modifies tracked files before the branch
checkout/pull, causing 'changes would be overwritten' errors and
leaving the branch behind remote. Stash before fetch/pull/checkout
and pop afterwards to ensure clean merge before push.
