Enum ChatEvent 

pub enum ChatEvent {
    Delta(String),
    ToolCall(ToolCall),
    Done,
    Error(String),
}

Streaming chat event.

Why: replaces the previous “string-only” channel so callers can distinguish text deltas from tool invocations and from terminal success/error without parsing magic markers out of the text stream. What: Delta is a content chunk; ToolCall is a fully-accumulated tool invocation; Done signals the upstream stream terminated normally; Error carries a human-readable message for stream-mid failures (the provider also returns Err from chat_stream, but Error lets the caller display partial-stream failures inline). Test: ollama_provider_streams_sse_deltas.
