Replace Jest with `vp test` (Vitest) and pretty-quick/Prettier with `vp fmt` (Oxfmt). Test and format config moves into vite.config.ts, so jest.config.js, .prettierrc and .prettierignore are removed.
Apply Oxfmt formatting across the repo now that Prettier is replaced by `vp fmt`. Also update the README testing docs to reference Vitest.
Introduce a `build` npm script (`webpack --mode production`) and call it from the Makefile instead of invoking webpack directly.
Add a `build:dev` script (`webpack --mode development`) and have the Makefile use it when DEBUG is set, restoring the development-mode build dropped when webpack invocation moved into the build script.
Replace the webpack/babel-loader build with `vp build` (Vite/Rolldown). Each UI page still ships a self-contained classic script, so the two entries are built as separate IIFE bundles (one `vp build` per entry, selected via --mode) into ui/.build/ui/js, matching the previous output that ui/ui.go inlines into a <script> tag. JSX is handled by esbuild's classic runtime targeting the global `React` (loaded via react-*.min.js), so no `react` import is injected and Babel is no longer needed. The two JSX entries are renamed to .jsx; build/test/ format config lives in vite.config.ts. Removes @babel/*, babel-loader, webpack, webpack-cli and webpack-dev-server.
Replace the per-entry --mode invocations with Vite's Environment API: each entry is its own IIFE build environment and builder.buildApp builds them in a single `vp build`. JSX config moves to the oxc.jsx block (Vite 8 uses the Oxc transformer), and build:dev switches to --mode development for the unminified build.

Migrates the UI build and test tooling from webpack/Babel/Jest to Vite+ (Rolldown, Vitest, Oxc, Oxfmt), building both self-contained IIFE bundles in a single
vp buildvia per-entry build environments. Also drops Babel/pretty-quick and wires the new build/test scripts into the Makefile.What kind of change does this PR introduce? (check at least one)
