Azhagammal 4d9c0b0883 fix[core]: added error message if the query vector or embedding contains NaN values (#31822) ...

**Description:**  
Added an explicit validation step in
`langchain_core.vectorstores.utils._cosine_similarity` to raise a
`ValueError` if the input query or any embedding contains `NaN` values.
This prevents silent failures or unstable behavior during similarity
calculations, especially when using maximal_marginal_relevance.

**Issue**:
Fixes #31806 

**Dependencies:**  
None
