CI check: the current red Tests jobs do not appear to come from this docs-only diff (docs/extending-locust.rst).

What I checked:

• This PR: Python 3.11 and 3.13 fail in StandaloneIntegrationTests.test_error_when_locustfiles_directory_is_empty with return code -2 instead of 1.
• Latest master Tests run 26369517649 at d90bc90a700b429ba64c84c432e80a3dfcd30ecf fails the same empty-directory test on Python 3.10, 3.11, 3.13, and 3.14.
• This PR's Python 3.14 job instead hit TestHttpSession.test_event_measure with a timing value just above the assertion window; that is also outside the docs file changed here.

All non-matrix checks I saw for this PR are green, including Ruff, Mypy, Docs Build, Linux, Windows, Docker image tests, and ReadTheDocs.
