Closes #35727 --- Several internal code paths raised a bare `ValueError` with no message, so when one of these conditions tripped, users saw a traceback with no explanation of what actually went wrong. This adds descriptive messages to each of those `raise ValueError` calls: - `FewShotPromptWithTemplates._get_examples` / `_aget_examples` — when neither `examples` nor `example_selector` is set. - Prompt `loading` — when a referenced template file uses an unsupported (non-`.txt`) format. - The LangSmith document loader — when both `client` and `client_kwargs` are supplied. - The Anthropic file-search middleware brace expansion — for unbalanced or empty brace patterns.

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.
