Single-directory package-test planner: discovers *.ww, groups white-box and external <pkg>_test sources, composes the combined test package, builds it through the sibling ww driver, and runs it with the runtime's -package/-list/-timeout-ms contract. test/package holds its E2E corpus and the manual runtime fixture set.
