v0.2.0

[0.2.0] - 2026-06-11

Added

• mDNS / zeroconf discovery. The server advertises itself as
  _zerod._tcp.local. via a new zerod-discovery crate (pure-Rust
  mdns-sd, no Avahi / Bonjour). The instance name defaults to the
  machine hostname and the published TXT records include the daemon
  version.
• zerod discover subcommand — lists every responder on the LAN
  with name, host, port, and advertised version.
• --name / ZEROD_NAME flag — when multiple servers respond,
  pick one by its mDNS instance name.
• --discover-timeout-ms / ZEROD_DISCOVER_TIMEOUT_MS flag —
  override the default 1500 ms browse window.
• [mdns] section in zerod.toml — enabled (default true) and
  name (empty → hostname).

Changed

• --host is now optional. Omitting it (and ZEROD_HOST) triggers
  mDNS discovery and connects to the only responder. Previously it
  defaulted to localhost.
• IPv4 address selection during discovery skips loopback and Docker's
  172.17.0.0/16 default bridge, so zerod running inside Docker or
  next to a docker0 interface no longer leaks the bridge IP to clients.
• zerod service install post-install hint now reflects the
  discovery-first UX (zerod system health instead of
  zerod --host <pi> system health).
