Again let's revert this commit. I think this is where we should make the purpose of heterophony{2,3}.list clearer. When a character-reading pair is added to heterophony1.list, it causes all other homophone readings to be pushed down to a very low score, and for very common characters (think of 中) that can be problematic, and this is where the "promotion by discounting the score of the highest homophone's reading" comes in. Further work on the documentation (and some tweaks of code review agent instructions), I'd say.

yes, let's refresh the documentation here https://github.com/openvanilla/McBopomofo/wiki/%E8%A9%9E%E5%BA%AB%E9%96%8B%E7%99%BC%E8%AA%AA%E6%98%8E#%E7%A0%B4%E9%9F%B3%E5%AD%97%E8%A9%9E%E9%A0%BB%E8%AA%BF%E6%95%B4 as well as update the AI reviewer's instructions https://github.com/openvanilla/McBopomofo/blob/master/Source/Data/AGENTS.md#handling-heterophony-characters-%E7%A0%B4%E9%9F%B3%E5%AD%97

Let's be explicit and crystal clear on the expected frequency change behaviors when editing these files.

Done updating the wiki and ask PR makers to ignore automated review suggestions, and made #739.
