Download session history
Download a session's message history. Formats: 'trace' (default — every message fully serialized, including tool calls, tool results, reasoning, and token usage), 'messages' (just the user/agent conversation turns as plain text), 'markdown' (the conversation rendered as a readable transcript), or 'stats' (aggregate metrics: message/tool-call counts, token usage, duration). All formats return JSON except 'markdown', which returns text/markdown.
