_run_git used subprocess.run(text=True) without an explicit encoding, so on
Chinese Windows (and other non-UTF-8 codepages) git stdout was decoded with the
locale codepage. _dirty_suffix() runs `git diff --binary HEAD`, whose binary
bytes are not valid GBK, raising UnicodeDecodeError in the subprocess reader
thread. That left r.stdout = None, so `r.stdout.strip()` raised AttributeError
during module import of api.updates, crashing server.py before it could bind
its port.
Force UTF-8 decoding with errors=replace and guard against None defensively.
