研究方向

The issue proposes that opt should remember where options were defined. To start, explore how options are currently defined and retrieved in ParlAI's opt.py and related files. Look at the existing opt system in `parlai/core/params.py` or `opt.py` to understand the current pattern. Consider how a 'source' attribute could be added to options without breaking existing usage. This would improve developer experience by making it easier to locate option definitions.
