/// Rewrite tool-call / tool-result messages into neutral transcript text.
///
/// This is a legacy compatibility adapter for OpenAI-compatible endpoints
/// that reject the standard multi-turn tool-calling protocol (`role: "tool"`
/// messages). It keeps assistant prose but drops assistant tool-call protocol
/// events so the model does not learn an assistant-authored tool-event
/// completion pattern. Tool results become user-side observations.
