-`Event::SessionConfigured` is emitted once after `Op::ConfigureSession`.

-Notable fields:
-- `session_id`: the backend-assigned session identifier (historically named `session_id` for
-  backwards compatibility).
-- `model_family`: model metadata for the model family selected for the session. This matches the
-  `/models` payload shape; the selected model slug is `model_family.slug`.
-- `approval_policy`, `sandbox_policy`, `cwd`: the effective execution and sandbox settings for the
-  session.
