Subject: [PATCH] fix(ai-adapter): send catch up summaries as a one-shot prompt

summarize() put the transcript in the prompt and also passed the same
messages as context.history, so every adapter sent the latest messages
twice and appended the instruction to the conversation. Send empty
history like getSuggestions(), keep roomId/userId/metadata, and mark the
transcript as chat data.
