Web viewer fails to build with vite during dev

[jprochazk]

vite does not properly copy the .wasm file when the @rerun-io/web-viewer dependency is optimized:

• new URL(foo, import.meta.url) doesn't work when dependency was optimized vitejs/vite#8427

This results in web viewer being unable to load the .wasm file at runtime during vite dev.

The workaround is to disable optimization for the package:

return defineConfig({
  optimizeDeps: {
    exclude:
      process.env.NODE_ENV === "production" ? [] : ["@rerun-io/web-viewer"],
  },
});

vite build works fine, because the .wasm file is properly copied into dist
