SignatureRepair — LangChain.js middleware fixing Gemini 3.x thought_signature drops on streamed tool calls

Workaround for langchain-ai/langchainjs#9624.

The bug

Gemini 3.x (gemini-3-flash-preview, gemini-3.1-flash-lite, gemini-3.5-flash, …) requires that every replayed functionCall part carries back the thoughtSignature it was issued with.
