JSON serialization in FieldInfoModel causes unnecessary double conversion in generators

[azmeuk]

FieldInfoModel converts values (default, examples) to JSON strings at model creation. Generators needing native values
(e.g., TOML) must json.loads() them back, then re-serialize to their target format.

I suggest that FieldInfoModel keep raw values instead of JSON serialized values, and raw annotations, and let the generator handle these raw data as they need.
