core: allow mermaid node labels to have any characters (#21385)
- it's only node ids that are limited

Thank you for contributing to LangChain!

- [ ] **PR title**: "package: description"
- Where "package" is whichever of langchain, community, core,
experimental, etc. is being modified. Use "docs: ..." for purely docs
changes, "templates: ..." for template changes, "infra: ..." for CI
changes.
  - Example: "community: add foobar LLM"

with
    - **Description:** a description of the change
    - **Issue:** the issue # it fixes, if applicable
    - **Dependencies:** any dependencies required for this change

core[patch]: utils.guard_import fix (#21133)
Issues (nit): 
1. `utils.guard_import` prints wrong error message when there is an
import `error.` It prints the whole `module_name` but should be only the
first part as the pip package name. E.i. `langchain_core.utils` -> print
not `langchain-core` but `langchain_core.utils`. Also replace '_' with
'-' in the pip package name.
2. it does not handle the `ModuleNotFoundError` which raised if
`guard_import("wrong_module")`

Fixed issues; added ut-s. Controversial: I've reraised
`ModuleNotFoundError` as `ImportError`, since in case of the error, the
proposed action is the same - we need to install a missed package.

Ignore self/cls from required args of class functions in convert_to_openai_tool (#20691)
Removed redundant self/cls from required args of class functions in
_get_python_function_required_args:

```python
class MemberTool:
    def search_member(
            self,
            keyword: str,
            *args,
            **kwargs,
    ):
        """Search on members with any keyword like first_name, last_name, email

        Args:
            keyword: Any keyword of member
        """

        headers = dict(authorization=kwargs['token'])
        members = []
        try:
            members = request_(
                method='SEARCH',
                url=f'{service_url}/apiv1/members',
                headers=headers,

            logger.info(e.__doc__)

        return members

convert_to_openai_tool(MemberTool.search_member)

expected result:

core[patch]: improve comma separated list output parser to handle non-space separated list (#20434)
- **Description:** Changes
`lanchain_core.output_parsers.CommaSeparatedListOutputParser` to handle
`,` as a delimiter alongside the previous implementation which used `, `
as delimiter.
- **Issue:** Started noticing that some results returned by LLMs were
not getting parsed correctly when the output contained `,` instead of `,
`.
  - **Dependencies:** No
  - **Twitter handle:** not active on twitter.

core[minor],langchain[patch]: Move base indexing interface and logic to core (#20667)
This PR moves the interface and the logic to core.

The following changes to namespaces:


`indexes` -> `indexing`
`indexes._api` -> `indexing.api`


Testing code is intentionally duplicated for now since it's testing
different
implementations of the record manager (in-memory vs. SQL).

Common logic will need to be pulled out into the test client.


A follow up PR will move the SQL based implementation outside of
LangChain.

core[patch]: Remove autoupgrade to addable dict in Runnable/RunnableLambda/RunnablePassthrough transform (#20677)
Causes an issue for this code

```python
from langchain.chat_models.openai import ChatOpenAI
from langchain.output_parsers.openai_tools import JsonOutputToolsParser
from langchain.schema import SystemMessage

prompt = SystemMessage(content="You are a nice assistant.") + "{question}"

llm = ChatOpenAI(
    model_kwargs={
        "tools": [
            {
                "type": "function",
                "function": {
                    "name": "web_search",
                    "description": "Searches the web for the answer to the question.",
                    "parameters": {
                        "type": "object",
                        "properties": {
                            "query": {
                                "type": "string",
                                "description": "The question to search for.",
                            },
                        },
                    },
                },
            }
        ],
    },
    streaming=True,
)

parser = JsonOutputToolsParser(first_tool_only=True)

llm_chain = prompt | llm | parser | (lambda x: x)


for chunk in llm_chain.stream({"question": "tell me more about turtles"}):
    print(chunk)

# message = llm_chain.invoke({"question": "tell me more about turtles"})

# print(message)
```

Instead by definition, we'll assume that RunnableLambdas consume the
entire stream and that if the stream isn't addable then it's the last
message of the stream that's in the usable format.

---

If users want to use addable dicts, they can wrap the dict in an
AddableDict class.

---

Likely, need to follow up with the same change for other places in the
code that do the upgrade

Important considerations:
- Parsing logic occurs within different providers;
- ~Changing output type is a breaking change for anyone doing explicit
type checking;~
- ~Langsmith rendering will need to be updated:
https://github.com/langchain-ai/langchainplus/pull/3561~
- ~Langserve will need to be updated~
- Adding chunks:
- ~AIMessage + ToolCallsMessage = ToolCallsMessage if either has
non-null .tool_calls.~
- Tool call chunks are appended, merging when having equal values of
`index`.
  - additional_kwargs accumulate the normal way.
- During streaming:
- ~Messages can change types (e.g., from AIMessageChunk to
AIToolCallsMessageChunk)~
- Output parsers parse additional_kwargs (during .invoke they read off
tool calls).

core[patch]:: XML parser to cover the case when the xml only contains the root level tag (#17456)
Description: Fix xml parser to handle strings that only contain the root
tag
Issue: N/A
Dependencies: None
Twitter handle: N/A

A valid xml text can contain only the root level tag. Example: <body>
  Some text here
</body>
The example above is a valid xml string. If parsed with the current
implementation the result is {"body": []}. This fix checks if the root
level text contains any non-whitespace character and if that's the case
it returns {root.tag: root.text}. The result is that the above text is
correctly parsed as {"body": "Some text here"}
