Complete Rust rewrite of the Go envd guest daemon that runs as PID 1 inside Firecracker microVMs. Feature-complete across all 8 phases: - Health, metrics, and env var endpoints - Crypto (SHA-256/512, HMAC), auth (secure token, signing), init/snapshot - Connect RPC via connectrpc + buffa (process + filesystem services) - File transfer (GET/POST /files) with gzip, multipart, chown, ENOSPC - Port subsystem (/proc/net/tcp scanner, socat forwarder) - Cgroup2 manager with noop fallback - Snapshot/restore lifecycle (conntracker, port subsystem stop/restart) - SIGTERM graceful shutdown, --cmd initial process spawn - MMDS metadata polling for Firecracker mode 42 source files, ~4200 LOC, 4.1MB stripped release binary. Makefile updated: build-envd now targets Rust (musl static), build-envd-go preserved for Go builds.
