Mohd KaifandClaude Sonnet 4.6 892ff4b4a7 fix(export): fix OWLExporter Turtle invalid syntax and silent data-property omission (#478) (#479) ...

- Add _ttl_block() helper to accumulate all predicate-object pairs before
  writing, producing a single valid Turtle subject block terminated by one
  period — eliminates the bug where rdfs:subClassOf / domain / range were
  appended after a closed '.' block
- Add missing data_properties loop to _export_owl_turtle so
  owl:DatatypeProperty declarations are no longer silently dropped
- Add _escape_ttl_str() to escape quotes, backslashes, newlines, carriage
  returns, and tabs inside Turtle string literals (rdfs:label, rdfs:comment,
  owl:versionInfo)
- Unify optional-field null checks to consistent x = prop.get(); if x: pattern
- Add 43 tests in tests/export/test_owl_exporter.py covering syntax validity,
  data properties, string escaping, null handling, and header output
- Update CHANGELOG.md with [Unreleased] entry

Closes #478
