fix(init): use bin.js entry point for TypeScript loader in justfile (#1252)

Closes #1251 

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