Bumps pytest-rerunfailures from 16.4 to 16.6.

Sourced from pytest-rerunfailures's changelog.

16.6 (2026-08-17)

Features ++++++++

• Add a repeatable --rerun-exclude-path option to exclude test files or directories from reruns. ([#232](https://github.com/pytest-dev/pytest-rerunfailures/issues/232) <https://github.com/pytest-dev/pytest-rerunfailures/issues/232>_)

Bug Fixes +++++++++

• Fix a regression in version 16.5 which made --pdb unusable even when no reruns were configured. ([#342](https://github.com/pytest-dev/pytest-rerunfailures/issues/342) <https://github.com/pytest-dev/pytest-rerunfailures/issues/342>_)

16.5 (2026-08-13)

Features ++++++++

• Add --max-suite-reruns option to cap the total number of reruns across the entire test suite. Once the limit is reached, no further reruns occur regardless of per-test --reruns or @pytest.mark.flaky settings. ([#298](https://github.com/pytest-dev/pytest-rerunfailures/issues/298) <https://github.com/pytest-dev/pytest-rerunfailures/issues/298>_)

Bug Fixes +++++++++

• Create a new test class instance for each rerun. Previously the instance of the failed attempt was reused, so state stored on self leaked into the rerun and broke test isolation. Fixtures cached at class scope or higher are still not re-executed. ([#268](https://github.com/pytest-dev/pytest-rerunfailures/issues/268) <https://github.com/pytest-dev/pytest-rerunfailures/issues/268>_)
• Prevent a rerun when a fixture teardown raises an error matching --rerun-except. Previously only the error from the current test stage was considered, so a --rerun-except-matching error raised during teardown was ignored and the test was rerun anyway. ([#270](https://github.com/pytest-dev/pytest-rerunfailures/issues/270) <https://github.com/pytest-dev/pytest-rerunfailures/issues/270>_)
