• Fix: graphify.serve now imports cleanly on Python 3.12 and 3.13. The chinese extra pins jieba-py from 3.12 onward (0.9.60 mistakenly kept the old jieba until 3.14, and its invalid regex escapes are a hard error on 3.12+), and the jieba import now suppresses the tokenizer's SyntaxWarning regardless of message or line so it never escalates under -W error.
• Fix: the git hook's rebuild-root guard now rejects a symlink-loop or dangling .graphify_root on Python 3.13, whose Path.resolve() no longer raises on a loop — the saved root must resolve to a real directory inside the repo before it is adopted.
