With pytest-github-actions-annotate-failures==0.4.0, failed tests can emit duplicate ::error workflow commands under xdist. With 0.3.0, the annotation is emitted once.

Reproduction

# sample.py
def test():
    assert 0

GITHUB_ACTIONS=true uvx \
--with pytest-github-actions-annotate-failures==0.4.0 \
--with pytest-xdist \
pytest sample.py -n 2

Output:

❯ GITHUB_ACTIONS=true uvx --with pytest-github-actions-annotate-failures==0.4.0 --with pytest-xdist pytest sample.py -n 2

Fix

• Register annotation hooks only on the controller process when xdist is active. Workers skip registration because the controller re-emits their reports.
• I had to fix tox.ini: it used groups = test, but tox has no such key. PEP 735 dependency groups are exposed as
  dependency_groups, so the test deps were never installed.
