LLMStreamEvent class

LLMStreamFinalResult is deleted: the stream terminates with the same LLMGenerationResult type the unary call returns (see result below), so one mapper serves both paths instead of two near-identical ones.

Exactly one terminal event per stream: event_kind == COMPLETED (with result set) or == ERROR (with error set). event_kind is the primary discriminator.
