Description
Concurrent Vitest processes sharing a fresh report directory can both pass the
existsSync()check increateReport(). One then fails withEEXISTwhen creating.vitestor its scoped directory. With the default blob reporter, this can leave a shard without a report even when its tests passed. The blob reporter started using this helper in #10232.This PR replaces the separate existence checks and directory creation calls with
mkdirSync(reportDir, { recursive: true }), which creates the parent directory and tolerates directories created by another process.Basically it's a rare race condition.
