// Copies the one real runtime dependency the CLI bundle can't statically
// inline (libsodium-wrappers, and its own dependency libsodium) next to
// the bundle, so dist-bundle/ is a small, complete, self-contained
// directory -- no npm install needed wherever it ends up.
//
// Why not just bundle it: libsodium-wrappers' published ESM build follows
// a relative import ("./libsodium.mjs") that's broken in that package's
// own dist layout -- the exact bug crypto.ts's own comment documents.
// Forcing static inlining via a literal require() (the only way to route
// esbuild's resolver to the *working* CJS build instead) was tried and
// technically resolved, but produced "No secure random number generator
// found" at runtime -- inlining the WASM engine breaks its own Node
// crypto feature-detection. Shipping the real, unmodified package files
// is more reliable than fighting that.
