npx blueprint test should probably re-build contracts before running tests

[anton-trunov]

It's a common issue when people forget to rebuild their contracts after modifying the source code and then run tests which fail or do not show debugging information.

I'd propose to change the default behavior to always re-build contracts before running tests and introduce a CLI flag to revert to the current workflow, e.g. npx blueprint test --no-build.

It will be better to replace jest with vitest and write vite plugin.
