Add the agent History tab -- every user's conversations with this agent, with rating, summaries, topic tags, and filters (user, date range, sentiment, topics). The transcript panel shows the conversation the way the chat did: attachments the user and agent exchanged, the Retrieved Documents the answer cited, the tools it called, and a per-turn Show Details panel with the model, temperature and request context. Includes a pagination slot and an optional export. This is one tab in the wider agent-settings family. All tabs share the same AgentSettingsProvider wrapper.
