Replace uv sync with uv pip install --group for dependency groups

uv pip install --group reads dependency groups directly from
pyproject.toml. Combined with positional package args, a single call
installs both the wheel and its test deps:

  uv pip install ./artifact.whl --group pyproject.toml:test

This eliminates uv sync and its --frozen, --inexact, --package,
--only-group, --no-install-project flags entirely from CI.
