SmolVM Enables Cross-Platform Agent Sandbox Dev

The author points out that you no longer need a dedicated Linux server just to develop a Firecracker-bound agent sandbox.
SmolVM is designed to use:
- QEMU + Hypervisor.framework on macOS
- Firecracker + KVM on Linux
- It exposes the same sandbox API externally
- Developers can run it locally on Mac, test on Linux, and finally deploy with Firecracker
The core philosophy is that applications should only care about "needing a sandbox," rather than the underlying VMM launching it.
