test(cli): route two merge-queue-flagged files to the integration tier

The partition pin caught both in the merge queue, on main after this
branch's base: test/build-multi-package-artifact.e2e.test.ts (new; spawns
the CLI through bin/run-dev.js under tsx) and
src/utils/schema-migration-plugins.declaration-boot-write-guard.test.ts
(existing; now constructs a real ObjectQL engine). Both join
INTEGRATION_FILES; the header's population line moves to the merged tree
(230 files = 158 unit + 72 integration).
