ak820-ctl: add version 0.1.0+git20260414main

CLI and GUI control software for the Ajazz AK820 Pro keyboard
(lighting, sleep timer, clock sync). Upstream has no tags, so the
source is pinned to a commit and nvchecker tracks the commit date.

Ships a uaccess udev rule for 0c45:8009, a desktop entry for
ak820-gui, and rc.ak820-lcd, a Slackware replacement for upstream's
systemd unit that runs the lcd subcommand in a restart loop.
