PR Summary

Medium Risk
Major-version upgrade of the test runner and coverage provider may change test/coverage behavior and cause CI failures, but it does not affect production runtime code paths.

Overview
Upgrades the monorepo’s test tooling by bumping vitest and @vitest/coverage-istanbul from 3.2.4 to 4.1.0 across multiple packages.

Updates yarn.lock accordingly, pulling in the new Vitest 4 dependency tree (notably updated coverage-related transitive deps such as @babel/core, magicast, and istanbul-reports).

Deprecated poolOptions config not updated for vitest v4

Medium Severity

Upgrading vitest to v4 in tests/hash-backend-integration/package.json without updating the corresponding vitest.config.ts, which uses poolOptions with singleThread and singleFork. These options are deprecated in vitest v4 (confirmed by v4.0.16 release note: "Log deprecated test.poolOptions if it's set"). This will emit deprecation warnings on every test run and the behavior may differ from v3, since vitest v4 replaced the underlying runtime from vite-node to module-runner. The v4 migration path is to use maxWorkers: 1 instead, though additional config may be needed to fully replicate v3's singleThread/singleFork semantics.
