ARK-OS remains a companion .deb layered on a base OS — not a full flash image. Add platform "modalix" for ARK Just a Jetson + Modalix SoM on eLxr 12 (aria): - Service user sima (SiMa default), not jetson/pi - Systemd unit set without jetson-can or rid-transmitter - FMU VBUS/reset helpers are no-ops until nRESET is mapped - Build baselines aria/bookworm (Python 3.11); preinst allows aria↔bookworm - install_ark_os.sh detects eLxr / Modalix DT model - CI matrix leg: arm64 debian:bookworm → ark-os-modalix-bookworm Document flash order: SiMa eLxr + ark-jaj.dtbo first, then this package.
install_ark_os.sh checked for a user named after PLATFORM (modalix), but the package runs as ARK_USER=sima on eLxr. Check the real service account instead.
Detect SiMa Modalix/eLxr correctly (do not treat Just a Jetson as NVIDIA). Populate model/module from device-tree and serial from AT24CSW unique ID. Report power draw from /run/ark-jaj/sys-power (INA238). UI hides L4T, JetPack, CUDA stack, and Jetson clocks on non-Jetson devices.
compatible is multi-string; use all tokens so module shows simaai,modalix-som instead of falling back to a generic label.
Expose optional power.voltage (V) and power.current (A) from the JAJ sys-power publisher / hwmon, and display them in the System UI when set.
Expose resources.disks (eMMC + NVMe etc.) from block devices and render a usage bar per disk. Unmounted drives show capacity as Not mounted.

Summary
ARK-OS is a Debian package of companion services (mavlink-router, web UI, video, log upload, etc.), not a full OS image. This PR adds a
modalixplatform so the same stack can run on SiMa Modalix + eLxr 12 (aria) — e.g. ARK Just a Jetson with Modalix SoM — after the SiMa base image is flashed.How to get it on a Modalix board
