feat: Add complete WireGuard protocol implementation

- Session management with key derivation
- Packet encryption/decryption using ChaCha20-Poly1305
- Cookie mechanism for DoS protection (MAC1/MAC2)
- Key generation utility
- Integrated with existing crypto suite (X25519, ChaCha20, Poly1305, BLAKE2s)
- Clean-room implementation based on RFC 9153
