    Client transport for SSE.

    `sse_read_timeout` determines how long (in seconds) the client will wait for a new
    event before disconnecting. All other HTTP operations are controlled by `timeout`.

    Args:
        url: The SSE endpoint URL.
        headers: Optional headers to include in requests.
        timeout: HTTP timeout for regular operations.
        sse_read_timeout: Timeout for SSE read operations.
        auth: Optional HTTPX authentication handler.
        on_session_created: Optional callback invoked with the session ID when received.
