Add openrgb-hue: Hue scene gradients for OpenRGB lights

Applies gradients derived from 103 bundled Philips Hue scenes to
OpenRGB-controlled LEDs, with six mapping modes (sequence, per-device,
per-zone, matrix, mirror, shuffle) and five animation modes (static,
scroll, pingpong, pulse, wave). Typer/Rich CLI with dry-run preview,
device/zone targeting, and a scenes-update command to refresh the
bundled dataset from its source gist.
