The docstring promises 'a single final terminal event' but the function accepted empty lists and sequences ending with non-terminal events. Add explicit checks for both cases.

The docstring for
validate_eventsinsrc/speechloom/streaming.pypromises to "require contiguous sequence IDs and a single final terminal event", but the implementation silently accepted:[]passes without error.[StreamEvent(0, "text", "hello")]passes even though it lacks adoneorcancelledevent at the end.This adds two explicit checks:
if not valuesrejects empty lists.if values[-1].kind not in ("done", "cancelled")rejects sequences that do not end with a terminal event.A new test file
tests/test_validate_events_terminal.pycovers both cases plus the valid done and cancelled terminal paths.
