This produces a standalone executable at **`release/proton-drive`** with embedded Bun. Add that directory to your `PATH`, or invoke it with a full path.

To build a plain JS bundle using a system-installed Bun instead:

```bash
cd ../sdk && bun install
cd ../cli && bun run build:bundle
```

This produces `release/proton-drive.js`. You are responsible for providing a wrapper to invoke it, e.g. `exec bun /path/to/proton-drive.js "$@"`.
