The workerd npm package's bin/workerd is a Node shim that execs the real binary from the per-platform optional dependency (@cloudflare/workerd-<os>-<arch>), which package-runtime.ts never copied into the image. Custom app tools failed to sync or invoke with 'workerd is unavailable on this platform'. Copy the platform package alongside the shim, derived per build platform like the libsql native addon.
