`Freestyle`, sandbox infra for coding agents with **~500ms** boot and memory-level forks

A full Debian VM can boot in ~500ms and fork the entire running state with about 400ms pause. Useful if you want agents to branch, snapshot, and resume real dev environments instead of toy serverless sandboxes.

[ KEY POINTS ]
  1. State cloning is not just filesystem copy: browser scroll, running processes, and in-memory errors carry over, which makes agent branching and rollback much more practical.
  2. The stack targets full Linux compatibility with hardware virtualization, eBPF, FUSE, multiple users, and systemd, so tools expecting a normal Debian box should need fewer hacks.
  3. They moved to bare metal because cloud node migration performance was not good enough. That hints this category may become infra-heavy and margin-sensitive fast.
  4. Positioning is closer to 'EC2 for agents' than lightweight preview sandboxes. The differentiator is runtime continuity, not just quick spin-up.
