Replace webpack with Vite 8 as the frontend bundler. Frontend build is around 3-4 times faster than before. Will work on all platforms including riscv64 (via wasm). `iife.js` is a classic render-blocking script in `<head>` (handles web components/early DOM setup). `index.js` is loaded as a `type="module"` script in the footer. All other JS chunks are also module scripts (supported in all browsers since 2018). Entry filenames are content-hashed (e.g. `index.C6Z2MRVQ.js`) and resolved at runtime via the Vite manifest, eliminating the `?v=` cache busting (which was unreliable in some scenarios like vscode dev build).
