This PR updates the on_tool_end handlers to return the raw output from the tool instead of casting it to a string.

Jan Nissen	b8922480ed	core[patch]: improve PydanticOutputParser typing (#18740) ... This PR adds generic typing to `PydanticOutputParser` so we get a typed output from `.parse` instead of `Any`. It should provide a better DX by way of Intellisense and for anyone strictly typing. Pre-change:  Post-change:  I haven't dug too deep, but I think a similar change could probably be added to `JsonOutputParser` so we don't have to pull up `.parse`.

Eugene Yurtsev	93472ee9e6	core[patch]: Replace memory stream implementation used by LogStreamCallbackHandler (#17185) ... This PR replaces the memory stream implementation used by the LogStreamCallbackHandler. This implementation resolves an issue in which streamed logs and streamed events originating from sync code would arrive only after the entire sync code would finish execution (rather than arriving in real time as they're generated). One example is if trying to stream tokens from an llm within a tool. If the tool was an async tool, but the llm was invoked via stream (sync variant) rather than astream (async variant), then the tokens would fail to stream in real time and would all arrived bunched up after the tool invocation completed.	5 months ago
