test(envd): add 136 unit tests across 12 modules
Cover all pure-function modules with inline #[cfg(test)] blocks:
crypto (NIST/RFC 4231 known-answer vectors), auth (SecureToken ops,
signature generation/validation), conntracker (snapshot lifecycle),
execcontext, util (AtomicMax concurrent correctness), http/encoding
(RFC 7231 negotiation), port/conn (/proc/net/tcp parsing),
rpc/entry (format_permissions), and permissions/path (tilde expansion,
ensure_dirs). Add tempfile dev-dep for filesystem tests. Update
Makefile test target to include cargo test.

feat: rewrite envd guest agent in Rust (envd-rs)
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.
