grabbit 66fa00aa1a feat(vida): add polygon mask to filter ground/obstacle false detections
Introduce configurable polygon masks that block ground, trees, and other
obstacles from triggering false meteor/fireball detections. Masks are
applied after thresholding but before morphology and line detection,
shared via Arc between both detectors. CLI supports --mask <json> flag.
