Move the platform detector to omarchy-settings with the guard

The settings package's platform guard runs omarchy-hw-platform before the
omarchy runtime is installed. omarchy leaves the detector out of its bin/
loop and settings ships it, with the /usr/share/omarchy/bin link the Apple
predicate and the CLI router use, whenever the source has it.
