Add comprehensive test coverage for Relations, Term, Importer, and REST Controller
Extends the test suite with 31 new tests covering: - Relations system (WithRelationships, HasManyAssociation, ManyToMany, RelationalQuery) - Builtin Term model (read-only WordPress term wrapper) - Importer (batch insert/update with dry-run support) - REST Controller (CRUD operations, route registration, error handling) Adds test helpers: Test_Parent_Model, Test_Child_Model, Test_Importer, Test_Controller. Note: Controller::test_get_items is skipped due to upstream bug where pagination params are passed as WHERE clauses to Query. Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
