v0.9.0

Added

• IPv6 dual-stack: deterministic ULA mesh addressing (fd99:6d67::/64) derived from Ed25519 public keys via Blake3. Dual-stack IPv4+IPv6 assigned to TUN interfaces on all platforms.
• FreeBSD support: tun(4) clone device with TUNSIFHEAD AF-family headers, ifconfig/route network configuration, poll-based event loop. Cross-compiles cleanly with zig build -Dtarget=x86_64-freebsd.
• IPv6 endpoint tracking in SWIM gossip protocol (addr6 field in Endpoint).
• IPv6 address/route management via rtnetlink (Linux), ifconfig (macOS/FreeBSD), netsh (Windows).
• SO_REUSEPORT support on FreeBSD (BSD socket option 0x0200).
• FreeBSD cross-compilation in build system (excluded from libsodium linkage and kernel WG interop).

Changed

• Zig 0.16: full port from Zig 0.15 (std.Io, std.process.spawn API changes).
• Endpoint struct now carries optional addr6 field for IPv6 peer addresses.
• UdpSocket extended with bindAddr6, recvFrom6, sendTo6 for IPv6 datagram handling.
• Binary wire protocol codec updated to serialize/deserialize IPv6 addresses.
• Version management: single source of truth in src/version.zig, validated by release CI.
• Release workflow: 6-target matrix (linux amd64/arm64, macOS amd64/arm64, FreeBSD amd64, Windows amd64).
• CHANGELOG.md introduced (retroactive to v0.3.0).

Fixed

• udp.zig pollRead now includes FreeBSD in the POSIX poll() branch (was compile error).
• build.zig unused is_macos variable removed.
