build(deps-dev): bump the python group across 1 directory with 3 updates

[dependabot]

Updates the requirements on pytest, mutmut and setuptools to permit the latest version.
Updates pytest to 9.1.1

Release notes

Sourced from pytest's releases.

9.1.1

pytest 9.1.1 (2026-06-19)

Bug fixes

• #14220: Fixed a logic bug in pytest.RaisesGroup which would might cause it to display incorrect "It matches FooError() which was paired with BarError" messages.
• #14591: Fixed a regression in pytest 9.1.0 which caused overriding a parametrized fixture with an indirect @​pytest.mark.parametrize to fail with "duplicate parametrization of '<fixture name>'".
• #14606: Fixed list-item typing errors from mypy in @pytest.mark.parametrize <pytest.mark.parametrize ref> argvalues parameter.
• #14608: Fixed a regression in pytest 9.1.0 where conftest.py files located in <invocation dir>/test* were no longer loaded as initial conftests when invoked without arguments. This could cause certain hooks (like pytest_addoption) in these files to not fire.

Updates mutmut to 3.6.0

Changelog

Sourced from mutmut's changelog.

3.6.0

* Add `# pragma: no mutate block` and `# pragma: no mutate start/end` comments


Add do_not_mutate_patterns to disable mutations with a regex


Add only_mutate config to select which files get mutated


Also mutate methods decorated with (only) @staticmethod or @classmethod


Add use_setproctitle option to disable process renaming (automatically disabled on MacOS)


Add (unstable) timeout_multiplier and timeout_constant options


Rename paths_to_mutate to source_paths


Deprecate tests_dir in favor of pytest_add_cli_args_test_selection


Change max_stack_depth to only consider functions inside source_paths


Disable mutation of enums and @staticmethod/@classmethod methods when type_check_command is set, as these mutations break type checking


Fix mutation for enum class methods


Fix mutate_only_covered_lines when project uses custom coverage.py config


Fix execution when running mutmut via python -m mutmut run


Fix mutation of class _SomePrivateClass class methods


Fix mutation of default args


Fix mutmut browse crash when no file is selected yet


Fix timeout checker looking up the wrong mutant's expected test time, which could cause mutants to hang


Compare stats paths after resolving symlinks


Warn when mutmut cannot match mutants with the collected stats


3.5.0

• Filter mutants based on type annotations. This feature needs to be turned on with the type_check_command config.

• Show error message when running on Windows

• Save mutation stats for use with CI/CD pipeline (#460)

Updates setuptools to 83.0.0

Changelog

Sourced from setuptools's changelog.

v83.0.0

Features

• Require Python 3.10 or later.

Bugfixes

• MANIFEST.in matching (via FileList) is now insensitive to Unicode normalization form. A pattern authored in one form (e.g. NFC, as typically saved by editors) now matches a file whose name is stored on disk in another (e.g. NFD, as produced by macOS APFS/HFS+). Previously an exclude, global-exclude, recursive-exclude, or prune rule could silently fail to drop a non-ASCII-named file from the source distribution, publishing it despite the exclusion -- see GHSA-h35f-9h28-mq5c.

Deprecations and Removals

• pypa/distutils#334

v82.0.1

Bugfixes

• Fix the loading of launcher manifest.xml file. (#5047)
• Replaced deprecated json.__version__ with fixture in tests. (#5186)

Improved Documentation

• Add advice about how to improve predictability when installing sdists. (#5168)

Misc

• #4941, #5157, #5169, #5175

v82.0.0
