Struct AgentRuntime 

pub struct AgentRuntime { /* private fields */ }

Runs user turns against one provider, tool registry, and context policy.

run_turn appends the user’s input to the session history, then repeats up to max_steps times:

1. the ContextPolicy selects the history that fits;
2. the Provider answers, streaming text as CoreEvent::AssistantDelta;
3. with no tool calls the turn is done; otherwise each call, in order, is checked by its tool, approved or denied by the ApprovalGate, and run, and its output is added to history for the next step.

Every step is reported to the EventSink. History stays within HistoryLimits by trimming old turns into a note. If the turn fails or is cancelled, history is restored to how it was before the turn.
