Code Review

This pull request updates the google-cloud-secret-manager library to version 2.26.0 across multiple files, including .librarian/state.yaml, the main CHANGELOG.md, and various gapic_version.py files within the package. The update to the package's CHANGELOG.md introduces features such as auto-enabling mTLS and checking Python/dependency versions in generated GAPICs. A review comment noted an inconsistency in the top-level CHANGELOG.md, where the previous version was incorrectly listed as 2.24.0 instead of 2.25.0, although the PR correctly updates it to 2.26.0.

[gemini-code-assist]

The previous version listed here was 2.24.0, but other parts of this PR (like the PR description and .librarian/state.yaml) indicate the previous version was 2.25.0. This top-level CHANGELOG.md seems to have been out of sync. While this PR correctly updates it to 2.26.0, the base version was incorrect.
