2.0 lac 模式不符合预期（['非货币', '性交易', '法则'], ['n', 'n', 'n']），seg模式正确（['非货币性交易', '法则']）。

Reproduce the reported input “非货币性交易法则” in lac 2.0 using both lac and seg modes, and compare the token and part-of-speech outputs with the 1.0 result shown in the issue. Start from the mode-specific segmentation and tagging entry points; done means lac mode matches the expected segmentation and tags while seg mode remains correct.
