Public history APIs should directly accept iterables of messages

[ncoghlan]

APIs accepting history inputs, including Chat.from_history, currently require multi-message histories to be formatted as full chat histories (Chat instances, or dictionaries with a messages key).

These APIs should also accept iterables of messages directly, treating those iterables as if they were the messages list in a full chat history.

Both input dictionaries and input messages should be annotated as accepting the shorthand form of simple text user messages, assistant responses, and system prompts (where the content field is simply the text of the message rather than a dict with type and text keys).

Ill take on this one since it seems straightforward and we are still thinking through the design for the other issue

[ArEnSc]

Just to communicate some expectations ill be back on this one soon.
I am working on a mail agent using the lm studio platform that is open source here https://github.com/ArEnSc/Chloe with another person, to solve a real life issue we have. The type script SDK is pretty decent, might have some feedback for that team sooner or later
