Describe the bug

If you run svelte-check whilst having a dev-server running, svelte-check will override the vite mode to production. This makes it so that you either have to kill the dev-server before running svelte-check, or restart it every time after running svelte-check.

Reproduction

1. Run vite dev
2. Run svelte-kit sync && svelte-check --tsconfig ./tsconfig.json
3. See that the mode of the vite-server has changed to production

Below is an example of screenshots showing that the environment is logged as development when starting the server, and inside the svelte-check process its logged as production. When visiting the dev-server after having ran svelte-check the configurations dependent on the environment has changed to production settings. Which in our case is the CSP-directives that are defined in the svelte-config.js file which are different between production and development enviroments.

Expected behaviour

I would expect to be able to run svelte-check whilst having a dev-server running without the environment being changed, or at least that its reset to development.
