Clear and concise description of the problem

• As a user
• I want to run vitest typecheck and vitest in just one command (e.g. just vitest or vitest --with-typecheck)
• so that I don't need to run e.g. two separate terminal windows in my VSCode editor in parallel to run all tests while I'm working on my project

Suggested solution

Run typecheck by default alongside the normal running tests by default.
(I use *.test-d.ts as recommended in the docs)

Alternative

Let us use a flag for running with typecheck via --with-typecheck (alternative wording welcome)
