v1.0.0

First stable release: reliable no-root LAN discovery plus port
scanning on macOS, Linux and Windows.

Discovery:

• The default TCP plus ARP engine sweeps a /24 in about 2 seconds,
  down from 494 seconds with naive ping sweeping. The TCP sweep finds
  hosts with open ports, and the ARP harvest pass catches quiet hosts
  that answer ARP but drop TCP. Harvest only candidates get a targeted
  probe before being reported, so stale table entries do not turn into
  false positives.
• The --ping fallback uses one ICMP ping per host for networks where
  TCP plus ARP does not fit.
• Results stream as hosts are found, then a sorted recap lists every
  host numerically with a one line summary of host count and elapsed
  time.

Scanning:

• Port scans share the TCP connect timeout, so filtered ports report
  quickly instead of stalling.
• Commands are unified under -s for discovery and -p for ports,
  with --help and --version alongside.

Platforms and toolchain:

• Ported to Zig 0.16.0.
• The Windows discovery path works natively, with a Winsock connect
  timeout, Windows arp -a parsing, and calmer WSA startup and
  cleanup.
• Linux is validated in the Docker lab (see docker/README.md),
  including an ip neigh fallback when arp is missing and per-OS
  ping wait flags.
• develop is merged into main, which is now the only long lived
  branch.
• CI builds and runs the tests on Linux, macOS and Windows.
