Turns out
ai.Tool.argswas trying to carry two unrelated things: user-defined tools' param spec, and provider-side tools' request-wise configuration. Also, typing didn't quite work anyway.This PR splits
ai.Tool.argsintoToolSpec(param spec and description used by server-side tools) andToolConfig. The latter can now also be used by server-side tools to set e.g. retry policy or other execution-related config.It also deletes provider-specific dataclasses and only leave factories for built-in tools.
