Subject: [PATCH] Fix PyPI wheel deps: add math-verify, cap transformers <5.13
 (bump 0.3.21)

The published wheel is built from pyproject.toml [project.dependencies], which
had drifted from requirements.txt. As a result `pip install optillm` shipped a
broken package:

- math-verify was missing entirely, so `import optillm` failed with
  ModuleNotFoundError (optillm.cepo imports math_verify at import time) -- the
  package would not even start.
- transformers was unpinned, so the mlx-lm cap added in 0.3.19 (requirements.txt
  only) never reached PyPI; installs pulled transformers 5.13.0 and broke mlx-lm
  on Apple silicon.

Sync the runtime deps into pyproject.toml:
- add math-verify
- transformers>=5.0.0,<5.13.0
- outlines[transformers]>=1.2.3

Verified by building the wheel and installing it into a clean venv (only its
declared deps) and importing optillm successfully.
