feat(langchain): extend dependency constraints to support LangChain 1.x

Extend LangChain dependency constraints to support both 0.x and 1.x versions:
- langchain: >=0.2.14,<0.4.0 → >=0.2.14,<2.0.0
- langchain-core: >=0.2.14,<0.4.0 → >=0.2.14,<2.0.0
- langchain-community: >=0.2.5,<0.4.0 → >=0.2.5,<2.0.0

Remove langchain-nvidia-ai-endpoints from optional dependencies as it
should be installed manually when needed.
