/**
 * Dedicated, serial project for the runner integration suite.
 *
 * `runner.integration.test.ts` starts real detached runner/session process
 * trees against the isolated temporary hub. It must never run inside the
 * default parallel unit-test suite (see the exclude in `vitest.config.ts`);
 * run it explicitly with:
 *
 *   bun run test:integration            # serial runner lifecycle coverage
 *   bun run test:integration:stress     # + the 20-session stress test
 *
 * The whole file runs in a single worker (`fileParallelism: false`) so
 * resource ownership stays unambiguous and the suite-level registry cleanup
 * (see `src/test/processRegistry.ts`) is authoritative.
