`_sanitize_chat_completions_content` now filters every content-part dict against an allowlist derived at import time from the `fireworks-ai` SDK's `ContentUnionMember1` TypedDict, and runs on every message role — not just `ToolMessage`. Fixes 400s of the form `Extra inputs are not permitted, field: 'messages[N].content.list[ChatMessageContent][i].<key>'` when cross-provider history (e.g. an Anthropic-shaped `AIMessage` carrying the v1 streaming-reassembly `index` marker) is forwarded to a Fireworks-hosted model.

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.
