Get Session State

Return the session's current state snapshot.

The shape matches the agent version's state schema (see GET /agents/{id}/versions/{version}/state-schema). Useful for inspecting the agent's running state — e.g., to read the latest values before sending the next turn.

Returns 409 if the session has no pinned agent version, or if the version is no longer available.
