v0.9.61

- 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.
