feat(conversations): add last message recontextualizer

[ludwiktrammer]

• I'll add the documentation in a separate PR (because landing the implementation itself in main is high priority)
• I'll add tests after refactor: merge llm client with llm #270 is merged (because they will involve creating a MockLLM class, which will be much easier after it is merged + doing it now will make merging it harder)
