Amazon QLDB API Rules

# amazon-qldb — 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: 50% of servers already https (warn)
#   - path-params-casing: snake @ 70% (n=20)
#   - query-params-casing: snake @ 47% (n=17)
#   - operationid-casing: pascal @ 100% (n=20)
#   - schema-names-casing: pascal @ 100% (n=82)
#   - schema-properties-casing: pascal @ 100% (n=102)
#   - security: global (root) — NOT emitting operation-security-required
#   - error-schema-defined: ErrorCause
#   - pagination params observed: ['max_results', 'next_token']
#   - merge: kept 19 existing, added 5 measured, upgraded 0
#   - added: query-params-casing, operationid-casing, schema-names-casing, schema-properties-casing, error-schema-defined
