Contract test references

• core.testing.extension-harness: ExtensionConformanceTest.php, ExtensionConformanceFailureTest.php

Stable entries have a direct contract test ID in the JSON catalogue. Experimental entries may change before the first public release. Internal entries are not extension APIs.

Compatibility enforcement is active in stable-extension-api-baseline.json; drift requires an explicit compatibility decision and is never silently reformatted away.
