Add host agent RPC server with sandbox lifecycle management

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.
