Dynamic in-situ character creation

Give characters (and regular chats) the ability to translate mentioned entities/people into venice characters. For example, during a roleplay with character A [a Venice character], character B [a part of the story] is mentioned. This feature request suggest adding a button called something like ‘Continue with B as new character’, which if clicked uses the context of character A combined with the full chat log as an input to an llm call to generate the required elements of character B. A new chat is then opened, perhaps with the exact same chat history, but where B is now a full Venice character who is the counterparty to the user's conversation.

Illustrative example: we are running a dinner party roleplay with character Alice as host. Alice introduces her sister Barbara who is fun to talk to. The user selects to continue the conversation with Barbara as new character, triggering a dynamic creation of new Venice character based on everything the context can tell us about Barbara plus some sensible extrapolation. The chat window switches to a conversation with Barbara.
