Implement the host agent as a Connect RPC server that orchestrates sandbox creation, destruction, pause/resume, and command execution. Includes sandbox manager with TTL-based reaper, network slot allocator, rootfs cloning, hostagent proto definition with generated stubs, and test/debug scripts. Fix Firecracker process lifetime bug where VM was tied to HTTP request context instead of background context.
