Code Review

This pull request updates the @langchain/anthropic package and adds support for the new Claude 4.5 Haiku models. The changes are a good step, but I've identified a critical issue with the pricing for the new models in models.json. The specified costs are higher than the official Anthropic pricing, which could lead to incorrect cost calculations for users. I've left suggestions to correct these values. Additionally, I found a related bug in packages/components/nodes/chatmodels/ChatAnthropic/FlowiseChatAnthropic.ts that was not part of this PR's changes. The logic for handling vision-capable models does not account for the new claude-4.5 models, which will cause issues with image uploads. I highly recommend addressing this oversight to ensure full and correct functionality for the new models.
