// Unit: provider registry dead-provider handling (Session 23).
//
// ParlayAPI was marked `status: 'dead'` after Chrome Claude confirmed its
// host no longer resolves. It must be excluded from every fallback chain
// and the configured-providers list, while still resolving via getProvider
// (the adapter + its mocked tests still reference the config).
