feat(vitest): add "strict" option to node environment

[sheremet-va]

Description

Currently Vitest "just works" when testing native Node.js applications even when the regular application would fail due to ESM incompatibilities. It is a good idea to run tests in the same environment where the actual application is running, but there are some pitfalls when providing such an environment.

This PR aims to cover all possible ESM/CJS issues that might arise when running code in Node.js env. For the first iteration, we assume that the code is bundled as ESM (even if tsconfig says otherwise).

Closes #2841
Closes #2198
