Summary of Changes

Hello @parthea, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request primarily consists of automated maintenance updates. It includes an update to a core Docker image, a significant refactoring of authentication parameter handling across multiple client libraries for consistency and clarity, an update to the Python version targeted by MyPy configurations, and the explicit declaration of a cryptography dependency in testing constraint files.

Highlights

Librarian Image Update: The python-librarian-generator Docker image used by the librarian tool has been updated to a new SHA256 hash in .librarian/state.yaml.
Authentication Parameter Refactoring: Numerous base.py files across various Google Cloud client libraries (e.g., Ad Manager, AI Generative Language, Analytics Admin, App Engine Admin, Asset, etc.) have been refactored. The scopes_kwargs dictionary is no longer used; instead, scopes, quota_project_id, and default_scopes are now passed directly to google.auth.load_credentials_from_file and google.auth.default functions.
MyPy Python Version Update: The mypy.ini configuration files for several packages have been updated to specify python_version = 3.14, indicating a forward-looking change for type checking.
Cryptography Dependency Addition: The cryptography package has been explicitly added as a direct dependency of google-auth in various testing/constraints-*.txt files across different Python versions.

Code Review

This pull request appears to be an automated update from the librarian tool. It includes several changes:

The generator image has been updated.
A large number of __init__ methods in transport base classes have been refactored to pass authentication scope arguments explicitly, which improves code clarity.
The cryptography dependency has been explicitly added to constraint files, which is a good practice for ensuring reproducible builds.

However, I've found a critical issue. The python_version in all mypy.ini files has been updated to 3.14, which is not a valid Python version. This will likely cause static analysis to fail or produce incorrect results. I've left comments on all affected files with a suggestion to fix this.
