+Colocate `src/vitest/` tests next to their sources (drop the
+`src/vitest/__tests__/` directory). Vitest discovers the test files
+via the existing `**/?(*.)+(spec|test).ts` include pattern, so the
+`**/__tests__/**/*.ts` entry has been removed from `vitest.config.ts`.
+The nested integration runner moves from
+`src/vitest/__tests__/integration/` to `src/vitest/integration/`. Pure
+refactor: no public API or behavior changes.
