Production build times extremely slow (10+ minutes for build + type checking)

8/10 High

Building for production takes ~10 minutes, and svelte-check adds another ~10 minutes, making it 20+ minutes total. esbuild, swc, and rspack lack good Svelte support, making workarounds difficult. Build times worsen as projects grow.
