test: Add integration test for research.googleblog.com parsing (issue #457)

[Copilot]

Articles from research.googleblog.com were parsed incorrectly — returning only the site tagline "The latest news from Research at Google" instead of actual article content.

Changes

• Added integration test test_issue_457_googleblog in tests/integration/test_article.py covering two representative article URLs from the Google Research Blog (domain now at blog.research.google.com)
• Test asserts extracted text exceeds 200 chars and does not consist solely of the site tagline

Related Issues

• fixes Build newspaper to get recent articles #457

Proposed Changes:

Adds a regression/integration test to document and validate correct parsing of Google Research Blog articles. No production code changes — this PR establishes the test baseline to expose the parsing failure.

How did you test it?

Integration test can be run locally with:

pytest tests/integration/test_article.py::TestArticle::test_issue_457_googleblog -v

Skipped automatically in GitHub Actions CI (per existing conftest.py pytest_runtest_setup hook).

Notes for the reviewer

The original domain research.googleblog.com has migrated to blog.research.google.com; test URLs reflect the current canonical domain. If the parsing bug is confirmed locally, a follow-up PR with a fix to the extraction logic will be needed.
