[Improve] Show Auto more of what the agent read

Auto was shown the newest 8 tool results and the first 1,500 characters
of each. When the agent looked a person or an item up in a longer
listing, or made a few more calls before using the id it found, the
lookup was cut off or dropped, so the model could not see what the id
referred to and asked for approval. It is now shown the newest 20
results, up to 6,000 characters of each and 16,000 across them.
