Amazon Aurora DSQL API Rules

# amazon-aurora-dsql — 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)
#   - servers-expected-domain: 1/1 servers on amazonaws.com
#   - path-params-casing: snake @ 57% (n=7)
#   - operationid-casing: camel @ 100% (n=11)
#   - schema-names-casing: pascal @ 100% (n=19)
#   - schema-properties-casing: camel @ 52% (n=48)
#   - security: global (root) — NOT emitting operation-security-required
#   - pagination params observed: ['maxResults', 'nextToken']
#   - merge: kept 10 existing, added 7 measured, upgraded 0
#   - added: servers-https-only, servers-expected-domain, path-params-casing, schema-names-casing, schema-properties-casing, security-schemes-defined, no-empty-descriptions
