[Bug]: Python 3.14 emits SyntaxWarning from pinned jieba dependency

[Yangtze-Seventh]

Area

src/everos

What happened?

When running EverOS in a Python 3.14 virtual environment, importing the default jieba-backed tokenizer emits SyntaxWarning messages from the pinned jieba==0.42.1 dependency.

EverOS declares requires-python = ">=3.12", so Python 3.14 currently appears to be accepted by the package metadata, but this dependency is not warning-clean under that runtime.

Expected behavior: running/importing EverOS should not emit dependency warnings on supported Python versions, or the supported Python range should exclude versions where the pinned dependency is not compatible yet.

Steps to reproduce

1. Create/use a Python 3.14 virtual environment.
2. Install EverOS dependencies from the current project configuration.
3. Run code that imports the jieba-backed tokenizer, for example anything that imports everos.component.tokenizer.jieba_provider or initializes the default tokenizer.
4. Observe the SyntaxWarning output from jieba.

Environment

OS: macOS
Python: 3.14
EverOS dependency: jieba==0.42.1 from pyproject.toml / uv.lock

  re_skip = re.compile("([a-zA-Z0-9]+(?:\.\d+)?%?)")

Possible fix

Consider one of the following:

• update or replace the pinned jieba dependency with a version that is warning-clean on Python 3.14;
• patch the relevant regex literals upstream / via a compatibility shim;
• narrow the declared Python support range until Python 3.14 is supported without dependency warnings.
