vitest.global-dir-setup.ts

// IMPORTANT: This file must run BEFORE any module that imports
// `core/util/paths.ts`, because that module resolves `CONTINUE_GLOBAL_DIR`
// into a constant at import time. If multiple test files (which run in
// parallel worker processes) all share the same global dir, they race on the
// same `globalContext.json` file on disk, causing flaky failures in the
// model-persistence tests.
//
// To guarantee isolation, give each worker process its own unique global dir.
// This file is intentionally dependency-free (no imports that transitively
// load `paths.ts`) and is listed first in `setupFiles` so the env var is set
// before any other module captures it.
