Bump pytest-rerunfailures from 15.1 to 16.4

[dependabot]

Bumps pytest-rerunfailures from 15.1 to 16.4.

Changelog

Sourced from pytest-rerunfailures's changelog.

16.4 (2026-07-01)

Breaking changes ++++++++++++++++

• Drop support for pytest 8.1. Minimum pytest version is now 8.2.

Features ++++++++

• Add support for pytest 9.1.

• Rerun tests with failed subtests. This feature is only available on pytest 9.0 and later. The pytest-subtests plugin is not supported. Fixes [#315](https://github.com/pytest-dev/pytest-rerunfailures/issues/315) <https://github.com/pytest-dev/pytest-rerunfailures/issues/315>_.

• Add --reruns-delay-backoff-factor option (and the matching reruns_delay_backoff_factor marker kwarg / ini setting) to grow the rerun delay after each attempt for an exponential backoff. The delay before the n-th re-run is reruns_delay * reruns_delay_backoff_factor ** (n - 1). The default factor is 1.0, so existing behaviour (a constant delay) is unchanged.

16.3 (2026-05-22)

Features ++++++++

• Add --reruns-mode option (strict or append). With append, marker reruns and the global --reruns / reruns ini setting are summed instead of the marker taking strict priority. Default is strict so existing behaviour is unchanged. Fixes [#321](https://github.com/pytest-dev/pytest-rerunfailures/issues/321) <https://github.com/pytest-dev/pytest-rerunfailures/issues/321>_.

• Add --rerun-show-tracebacks option to display tracebacks from failed attempts that were retried, including tests that eventually passed. The rerun summary section is emitted automatically when the flag is set, so -rR is no longer required to see the tracebacks. Fixes [#156](https://github.com/pytest-dev/pytest-rerunfailures/issues/156) <https://github.com/pytest-dev/pytest-rerunfailures/issues/156>_.
