/**
 * Package-shape override (see the root tsdown.config.ts): besides the
 * default lib/index.js bundle, the worker BOOTSTRAP ships as its own
 * sibling CommonJS entry — `new Worker(fileURLToPath(new URL('./worker.cjs', import.meta.url)))`
 * loads it as a file, so it cannot be part of the index bundle. pkg's VFS
 * Worker hook compiles string-path entries as CommonJS, so an ESM worker is
 * not viable inside the executable. TWO
 * single-entry builds, not one two-entry build: a multi-entry build emits
 * the shared bootstrap module as a `lib/bootstrap-*.js` chunk both bundles
 * import, which the package.json `files` whitelist (deliberately exact)
 * would omit from the packed artifact — each single-entry build inlines its
 * own bootstrap copy instead, keeping every shipped file self-contained.
