Subject: [PATCH] chore: record scope for ChatVertexAI labels fix (external
 repo)

Tracks issue 025b4ad7-09bd-475d-8343-f11940f7e22d. The actual fix
belongs in langchain-google-vertexai (chat_models.py) - pop `labels`
from the params dict before constructing GenerationConfig, since the
Vertex SDK no longer accepts `labels` on GenerationConfig; forward
it on the request envelope instead.
