Nick Hollon 9ab26d5e6d feat(core): add stream_events version='v3' overload
Adds @overload signatures to `Runnable.astream_events` and introduces a
new `Runnable.stream_events` sync method, both accepting `version='v3'`.
The base-class implementation raises `NotImplementedError` with a message
directing callers to use a subclass that implements the v3 streaming
protocol (BaseChatModel, CompiledGraph). v1/v2 behavior is unchanged.
