Closes #34207 --- Expose log probabilities from the Ollama Python SDK through `ChatOllama`. The ollama client already returns a `logprobs` field on chat responses for supported models, but `ChatOllama` had no way to request or surface it. ## Changes - Add `logprobs` and `top_logprobs` fields to `ChatOllama`, forwarded to the client via `_build_chat_params`. Setting `top_logprobs` without `logprobs=True` auto-enables it with a warning; setting it with `logprobs=False` raises a `ValueError` - Surface per-token logprobs on intermediate streaming chunks (both sync `_create_chat_stream` and async `_create_async_chat_stream`) via `response_metadata["logprobs"]`, accumulated into the final response on `invoke()` - Bump minimum `ollama` SDK from `>=0.6.0` to `>=0.6.1` — the version that added logprobs support --------- Co-authored-by: Mason Daugherty <mason@langchain.dev> Co-authored-by: Mason Daugherty <github@mdrxy.com>

This repository is structured as a monorepo, with various packages located in this libs/ directory. Packages to note in this directory include:
core/ # Core primitives and abstractions for langchain
langchain/ # langchain-classic
langchain_v1/ # langchain
partners/ # Certain third-party providers integrations (see below)
standard-tests/ # Standardized tests for integrations

(Each package contains its own README.md file with specific details about that package.)
Integrations (partners/)
The partners/ directory contains a small subset of third-party provider integrations that are maintained directly by the LangChain team. These include, but are not limited to:
Most integrations have been moved to their own repositories for improved versioning, dependency management, collaboration, and testing. This includes packages from popular providers such as Google and AWS. Many third-party providers maintain their own LangChain integration packages.
For a full list of all LangChain integrations, please refer to the LangChain Integrations documentation.
