Add test_quality tool implementing OQuaRE ontology quality evaluation

Implement the OQuaRE framework (based on ISO/IEC 25000 SQuaRE) as a new
MCP tool and CLI command. Uses whelk-rs for native OWL EL reasoning to
compute inferred class hierarchy, matching the behavior of the Java
reference implementation.

The tool computes 19 metrics, scales them to 1-5, aggregates into 22
subcharacteristics, 7 quality characteristics, and an overall OQuaRE score.
