nat_check v1.0.0

First modular release of nat_check — RFC-compliant NAT type detection for Linux.

Added

• Prebuilt, statically-linked nat_check-linux-x86_64 binary that runs on any x86_64 Linux distro with no dependencies.
• CMake build system with an optional fully-static build mode.
• --version flag.
• GitHub Actions: CI (build + smoke test) and an automated release pipeline.

Changed

• Rebuilt the single-file program into focused, maintainable modules (STUN protocol, UDP socket, NAT detection, CLI/output).
• Hardened STUN address parsing and command-line port validation.
