add early return to `storybookTest`, so when vite is running in non-vitest "mode" the plugin becomes a no-op.

The plugin should never be added if this condition is true, so it can be removed in the implementation
ndelangen
committed
move preset evaluation of `env` down, and set `BUILD_MODE` env variable prior to vitest's `mode`
ndelangen
committed
Update code/addons/vitest/src/vitest-plugin/index.ts
