PeopleSoft API Rules

# peoplesoft — 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:
#   - servers-https-only: 100% of servers already https (error)
#   - path-params-casing: camel @ 89% (n=18)
#   - query-params-casing: snake @ 62% (n=24)
#   - operationid-casing: camel @ 100% (n=60)
#   - schema-names-casing: pascal @ 100% (n=8)
#   - schema-properties-casing: screaming @ 100% (n=96)
#   - operation-security-required: 58/60 ops declare per-op security
#   - operation-documents-401: 97% adherence
#   - pagination params observed: ['maxResults', 'offset']
#   - merge: kept 19 existing, added 5 measured, upgraded 0
#   - added: query-params-casing, operationid-casing, schema-properties-casing, operation-security-required, operation-documents-401
