Argo CD API Rules

# argo-cd — 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 @ 77% (n=79)
#   - query-params-casing: snake @ 50% (n=283)
#   - merge: kept 18 existing, added 3 measured, upgraded 0
#   - added: path-params-casing, query-params-casing, no-empty-descriptions
