Anchore API Rules

# anchore — 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 example.com
#   - path-params-casing: camel @ 80% (n=5)
#   - query-params-casing: snake @ 80% (n=5)
#   - operationid-casing: camel @ 100% (n=11)
#   - schema-names-casing: pascal @ 93% (n=14)
#   - schema-properties-casing: snake @ 52% (n=68)
#   - security: global (root) — NOT emitting operation-security-required
#   - error-schema-defined: ErrorResponse
#   - merge: kept 9 existing, added 10 measured, upgraded 0
#   - added: servers-https-only, servers-expected-domain, path-params-casing, query-params-casing, operationid-casing, schema-names-casing, schema-properties-casing, security-schemes-defined, error-schema-defined, no-empty-descriptions
