Got tired of typing the same sync/clone/build commands for every
device, so now everything lives in config.json (codename, vendor,
tree repo, fox branch, build target, env vars).
The script handles:
- syncing fox sources via the official orangefox_sync.sh
- cloning/updating the device tree into device/<vendor>/<codename>
- exporting env vars from the json and running mka
Also supports -s/-c/-b flags to run each step separately.
