Trying to unblock documentation build pipeline
* Bump langgraph dep in docs
* Update langgraph in lock file (resolves an issue in API reference
generation)
I am modifying two things:
1. "This sample demonstrates" with "The following samples demonstrate"
as we're talking about at least 4 samples
2. Bringing the sentence to after talking about the definition of
textract to keep the document organized (textract definition then
samples)

* New `reasoning` (bool) param to support toggling [Ollama
thinking](https://ollama.com/blog/thinking) (#31573, #31700). If
`reasoning=True`, Ollama's `thinking` content will be placed in the
model responses' `additional_kwargs.reasoning_content`.
* Supported by:
* ChatOllama (class level, invocation level TODO)
* OllamaLLM (TODO)
* Added tests to ensure streaming tool calls is successful (#29129)
* Refactored tests that relied on `extract_reasoning()`
* Myriad docs additions and consistency/typo fixes
* Improved type safety in some spots
Closes#29129
Addresses #31573 and #31700
Supersedes #31701
Integrate Bandit for security analysis, suppress warnings for specific issues, and address potential vulnerabilities such as hardcoded passwords and SQL injection risks. Adjust documentation and formatting for clarity.

(shedding 8gb of required installs)
- bump deps (non-breaking) in anticipation of upcoming "thinking" PR

docs: update multimodal PDF and image usage for gpt-4.1
**Description:**
This update revises the LangChain documentation to support the new
GPT-4.1 multimodal API format. It fixes the previous broken example for
PDF uploads (which returned a 400 error: "Missing required parameter:
'messages[0].content[1].file'") and adds clear instructions on how to
include base64-encoded images for OpenAI models.
**Issue:**

Error code: 400 - {'error': {'message': "Missing required parameter:

Description:
This pull request corrects minor typographical errors in the
documentation notebooks for vectorstore integrations. Specifically, it
fixes the spelling of "datastore" in `llm_rails.ipynb` and
"pre-existent" in `redis.ipynb`. These changes improve the clarity and
professionalism of the documentation. No functional code changes are
included.
