Amazon App Runner API Rules

# amazon-app-runner — 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: 56% of servers already https (warn)
#   - query-params-casing: pascal @ 100% (n=32)
#   - operationid-casing: pascal @ 100% (n=71)
#   - schema-names-casing: pascal @ 100% (n=370)
#   - schema-properties-casing: pascal @ 100% (n=573)
#   - security: global (root) — NOT emitting operation-security-required
#   - error-schema-defined: InternalServiceErrorException
#   - merge: kept 3 existing, added 8 measured, upgraded 0
#   - added: servers-https-only, query-params-casing, operationid-casing, schema-names-casing, schema-properties-casing, security-schemes-defined, error-schema-defined, no-empty-descriptions
