fix(init): use bin.js entry point for TypeScript loader in justfile

`just init` fails because `node packages/tools/src/index.ts` runs
without a TypeScript loader, so Node.js cannot resolve `.js` imports
to `.ts` files. Use `bin.js` which registers `@oxc-node/core/register`
before importing `index.ts`.
