Azure Databricks API Rules

# microsoft-azure-databricks — 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 azuredatabricks.net
#   - query-params-casing: snake @ 100% (n=25)
#   - operationid-casing: camel @ 100% (n=32)
#   - schema-names-casing: pascal @ 100% (n=22)
#   - schema-properties-casing: snake @ 100% (n=187)
#   - security: global (root) — NOT emitting operation-security-required
#   - error-schema-defined: Error
#   - operation-documents-400: 84% adherence
#   - operation-documents-401: 100% adherence
#   - operation-documents-403: 94% adherence
#   - operation-documents-429: 100% adherence
#   - operation-documents-500: 100% adherence
#   - pagination params observed: ['limit', 'offset']
