Apache Hudi API Rules

# apache-hudi — 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:
#   - path-params-casing: camel @ 100% (n=5)
#   - operationid-casing: camel @ 100% (n=5)
#   - schema-names-casing: pascal @ 100% (n=6)
#   - schema-properties-casing: camel @ 76% (n=29)
#   - merge: kept 8 existing, added 5 measured, upgraded 0
#   - added: path-params-casing, operationid-casing, schema-names-casing, schema-properties-casing, no-empty-descriptions
