Change memo to no longer replay streams

[petersalas]

• Change the behavior of memo so that it only yields the most recently rendered frame, rather than replaying the entire stream. When combined with non-append-only streams + partial rendering the previous behavior could cause an exponential blowup in the number of frames.
• Change AI.AppendOnlyStream to be a function that takes a Node so that converting a stream to append-only does not require an extra yield (i.e. an extra frame).
• Change partial rendering to memoize returned elements, instead of simply binding the context, and remove the now-unneeded memos in conversation.tsx accordingly.
• Source the memoized ID from the render context so that it (can be) deterministic within a single RenderContext
• Add unit tests for memoize.tsx.
