v1.0.0

Added

• Config-flow setup: enter your gateway's IP address (defaults to
  192.168.1.254) and optionally a device name - no YAML required.
  Credentials aren't needed since this gateway's status pages don't require
  a login.
• Sensors for connection status, current time, system uptime, last reboot,
  external IP/IPv6 address, default gateway, primary/secondary DNS, and
  receive/transmit packet/byte/unicast counters; a connectivity binary
  sensor; and device info (manufacturer, model, hardware/software version,
  serial number, first use date) read directly from the gateway.
• Built on Home Assistant Core's built-in scrape/rest integrations - no
  separate HACS dependency to install.
