[Feature request] Treat TypeScript (and potentially other checker) errors as test failures when running Vitest

[treybrisbane]

Is your feature request related to a problem? Please describe.

Currently, when running Vitest with vite-plugin-checker configured, checker errors are only logged and do not fail the test run. This is particularly apparent when using the TypeScript checker, as tools like ts-jest treat type errors as test failures by default.

Describe the solution you'd like

An MVP would be:

• Detection of any TypeScript errors can (configurably) result in the whole Vitest run failing
• Behaviour is configurable via a boolean flag specific to the TypeScript checker

The ideal solution would be:

• Any checker errors can (configurably) result in failures of the individual tests (or test files) they appear in
• Behaviour is configurable via boolean flags specific to each checker implementation
