bahtyar bc21045ee0 fix(ollama): prevent _convert_messages_to_ollama_messages from mutating caller list (#36567)
Fixes #36564

The method modifies messages[idx] in-place when converting v1 format
content. Add messages = list(messages) to create a shallow copy before
any mutations.

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.
