Amazon Direct Connect API Rules

# amazon-direct-connect — 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)
#   - operationid-casing: pascal @ 100% (n=63)
#   - schema-names-casing: pascal @ 98% (n=248)
#   - schema-properties-casing: camel @ 81% (n=445)
#   - security: global (root) — NOT emitting operation-security-required
#   - error-schema-defined: StateChangeError
#   - merge: kept 18 existing, added 4 measured, upgraded 0
#   - added: schema-names-casing, schema-properties-casing, security-schemes-defined, error-schema-defined
