Bundled tsdown requires undeclared runtime dependency picomatch #1731
Description
Describe the bug
The bundled version of tsdown in Vite+ makes a require call to use picomatch. The following excerpt is from the distributed version of 0.1.23:
// @voidzero-dev\vite-plus-core\dist\tsdown\main-Cq8Is40L.js#L2,L11-L12
import { createRequire } from "node:module";
//#region ../../node_modules/.pnpm/tsdown@0.22.0_@arethetypeswrong+core@0.18.2_@tsdown+css@0.22.0_@tsdown+exe@0.22.0_@type_e80978d33a319eb1e0c97ec71b684e94/node_modules/tsdown/dist/general-D3muxt2f.mjs
const picomatch = createRequire(import.meta.url)("picomatch");As far as I can tell, this dates back to when #396 was merged - a quick look through the releases on NPM suggests that picomatch has never been correctly bundled and never been declared as a dependency.
