1.4.0

Minor Changes

• #11 9392d7e Thanks @TooTallNate! - Add optional file logging for the sysmodule. Since a sysmodule has no console
  output, diagnostics can now be captured by setting log = true in
  config.ini; output is appended to sdmc:/config/sys-autopilot/log.txt.
  Logging is off by default and gated at runtime, so it has no cost when unused.

• #10 4851df6 Thanks @TooTallNate! - Add mDNS / DNS-SD network discovery. The console now advertises itself on the
  local network as <hostname>.local and publishes the _sys-autopilot._tcp
  service with a TXT record describing the version/path/auth/model/firmware/
  Atmosphère version, so MCP clients and curl can target a stable name instead
  of a hard-coded IP.

  • New hostname key in config.ini. When blank it auto-generates
    switch-<last 4 of serial>, which is unique per console so two devices on
    the same network don't collide.
  • The LAN address is obtained from nifm (a sysmodule's gethostid() only
    ever returns loopback), with the server retrying until the interface is up.
  • New scripts/discover.sh helper browses for consoles on the LAN.
