fix: pytest plugin to fail tests when anybodycon is not available (#143)

* Initial plan

* Fix pytest plugin to fail tests when anybodycon is not available

Add early check in AnyTestItem.runtest() to raise a proper test
failure when the AnyBodyCon executable cannot be found, instead of
silently passing with an unhandled thread exception.

Also add test_no_anybodycon pixi environment and CI job to verify
.any tests correctly fail without anybodycon installed.

Fixes #142

* Address code review: fix pytest.fail() usage and simplify CI shell logic

* Change test-no-anybodycon CI job to run on windows-latest

Switch the runner from ubuntu-latest to windows-latest and add
shell: bash since the ! negation operator requires bash (not
PowerShell, the default on Windows runners).

* Rename pixi env to test-no-anybodycon (dashes) and run pixi lock

Pixi requires environment names to use only lowercase letters,
numbers and dashes. Renamed test_no_anybodycon to
test-no-anybodycon in pixi.toml and the workflow file, then ran
pixi lock to regenerate the lock file.

* Fix black formatting in pytest_plugin.py

Collapse multi-line if condition to single line to match
black's expected formatting and pass CI lint check.
