Pull request overview

This PR updates CASCaRA exports and validation to better support “configurable” package metadata (e.g., contributor/license) and improves TTL/JSON-LD/HTML export behavior, alongside a version bump and refreshed test fixtures.

Changes:

• Extend PIG constraint checks to validate enumerated properties/links on packages in addition to entities/relationships.
• Enhance TTL export with an explicit ontology header and improved SHACL constraint generation for external predicates.
• Add revision/UUID utilities and update fixtures/build metadata to reflect the new export format and release version.
