v2 todo list

[sashabaranov]

This discussion is to collect some things we'd like to see in an API-breaking v2 release

A few things top of my mind:

• omitempty option of request struct will generate incorrect request when parameter is 0. #9 + Make temperature and top-p consistent across the codebase
• Move most of the code into the internal/ directory?
• Better jsonschema+structured outputs based on Go struct tags (see comment)
