methaneset-emit level0: add match:pairs + match:orphans (explicit IMEO<->CM connections with iou/sector/dist_m); rename detection:imeo_cod/cm_cod -> match:imeo_cod/cm_cod; move source points to spatial:imeo_points/cm_points (spatial block now at the end); drop annotation:iou_pairs and match:n_instances; annotation:pct_imeo/pct_cm now percent (0-100). COLLECTION.json field_schema updated.
