Argo Workflows API Rules

# argo-workflows — Spectral ruleset (strengthened)
# Plain Spectral. Existing hand-authored rules preserved; measured rules added
# from this provider's own OpenAPI conventions by strengthen_ruleset.py,
# then self-validated against the spec.
#
# Provenance:
#   - path-params-casing: snake @ 88% (n=108)
#   - merge: kept 13 existing, added 2 measured, upgraded 0
#   - added: path-params-casing, no-empty-descriptions
