GCAP-SPEC-CONNECTOR-DESCRIPTOR-0001 implementation.
ConnectorPlugin — abstract base for governed connectors.
ConnectorRegistry — register/discover connectors.
ConnectorRuntime — wraps invoke with Chronicle lineage.
EchoConnector — dev/test example.
API endpoints:
GET /connectors/ — browse catalogue
GET /connectors/{id}/ — connector descriptor
POST /connectors/{id}/invoke/ — governed invocation
GET /connectors/{id}/health/ — health check
5 tests passing.
