Fix Schema.org property domain validation

[ziodave]

Summary

• validate Schema.org property domain compatibility across direct validation and graph audits
• generate compact domain metadata and synchronized subclass ontology data from the same official Schema.org graph
• report deterministic warning details for invalid property/type pairs, including subclass and multi-type handling
• refresh the bundled Schema.org grammar and document the behavior

Regression fixed

A schema:Service using schema:isPartOf now reports:

The property isPartOf is not recognized by the schema (e.g. schema.org) for an object of type Service.

Verification

• validation slice: 76 passed
• graph slice: 39 passed
• focused coverage suite: 51 passed
• changed-line coverage: 91.8%
• Ruff, formatting, and diff checks passed
• prepared validation benchmark: 0.129s per validation versus 0.133s before the change
• independent semantic and senior reviews completed with no blocking findings

Existing rdflib JSON-LD deprecation warnings remain unchanged.
