The ::warning:: wrapper kept the lane job green on failure — honest
about not gating merges, but a Windows regression was visible only as
an annotation buried in the run summary. GitHub has no yellow job
state, so the choice is green+annotation (too hidden) or a red X on a
non-required job (visible, still non-blocking). Take the red X:
job-level continue-on-error, plain 'Run gates' step, one less wrapper.
The step stays on the runner's native pwsh — never shell: bash — per
the MSYS-parent leak recorded in the windows-support RFC.
Also remove the temporary Windows-only failing demo test that
exercised the wrapper's annotation path (REVERT ME commit a496b9ae).
