//! Kimi-style stream event extraction.
//!
//! Responsibilities:
//! - Render role-based assistant content arrays with text and think entries.
//! - Render deferred tool calls carried in `tool_calls`.
//!
//! Does not handle:
//! - Claude/Codex event typing.
//! - Cursor nested tool call envelopes.
