AgentState class final

Public agent state. Ported from pi's AgentState.

Assigning tools or messages copies the provided top-level list. The runtime fields (isStreaming, streamingMessage, pendingToolCalls, errorMessage) are read-only for consumers; the owning Agent mutates them as it processes loop events.
