chore(deps): bump vitest and @vitest/coverage-v8 to 5.0.2

Patch release, bug fixes only, no breaking changes. Two entries are
relevant to this repository: a stack overflow when spying on
Set.prototype.add, and the hanging-process reporter switching to its ESM
entrypoint, which drops why-is-node-running 2.3.0, siginfo and stackback
in favour of why-is-node-running 3.2.2.

Verified with the CI unit command: 3302 tests pass under --maxWorkers=4,
the coverage run clears its thresholds, pnpm deps:audit reports no known
vulnerabilities, and the lockfile stays consistent under
--frozen-lockfile.
