Drops --persistence-spots and AdaptiveSpotFinderCPU::RunPersistence (the 0-D
topological-persistence detector added in 5a33b0743). It was a research variant
that never beat the hard-threshold adaptive detector on a CC1/2 basis and is a
GPU dead-end (global candidate sort + union-find), so it is not a production
path. The hard-threshold --adaptive-spots detector is unaffected.
