chore: update dependencies

[willkill07]

Overview

Refresh Python integration dependency floors and the generated dependency metadata that tracks them.

• I confirm this contribution is my own work, or I have the right to submit it under this project's license.
• I searched existing issues and open pull requests, and this does not duplicate existing work.

Details

• Update the langchain optional dependency floor from 1.3.2 to 1.3.4.
• Update the langchain-nvidia-ai-endpoints optional dependency floor from 1.4.0 to 1.4.1.
• Refresh uv.lock and ATTRIBUTIONS-Python.md for the resolved Python dependency versions.
• Validation: uv run pre-commit run --files ATTRIBUTIONS-Python.md pyproject.toml uv.lock.

Where should the reviewer start?

Start with pyproject.toml, then verify the generated uv.lock and ATTRIBUTIONS-Python.md updates are consistent with the dependency refresh.
