feat(sat): follow the azimuth only
A satellite tracker that insists on an elevation motor is a tracker switched off for nearly everybody. A pass at the edge of the footprint — which is most of them — never climbs above ten or fifteen degrees for its whole length, and a yagi's beamwidth swallows that: the bearing alone is enough, and it is how most stations that work satellites are actually built. The same switch rescues an az/el station whose elevation motor has failed. So it is an option, not a silent fallback, because it does cost something: a bird straight overhead is a moving azimuth and a bearing that means nothing, and whether to accept that is the operator's call. With it on, any rotor in the list can be chosen — the PstRotator, the Rotator Genius, the ARCO, the tower already turned for HF. That works because the per-backend command dispatch moved out of the three RotatorGoTo/Stop/Heading methods into linkGoTo/linkStop/linkHeading, so the satellite tracker drives any of the seven backends through the same code the compass uses instead of a second implementation of each. GetRotatorHeading loses sixty lines of near-duplicate switch in the process, and a rotor with no elevation axis now says so (HasElevation) rather than reporting a zero that looks like a real bearing. One trap, with a test on it: the step check compared both axes, so with the elevation never commanded its difference stayed above the step for the whole pass and every tick ordered the antenna to the bearing it was already on. A mast has a finite number of turns in it. Co-Authored-By: Claude Opus 5 (1M context) <[email protected]>
