Burned-area perimeter progression (raster -> vector)
Convert a stack of per-scene burn-probability rasters into one perimeter polygon per acquisition. Thresholds burn probability, drops small connected components, polygonizes the binary mask, simplifies with a Douglas-Peucker tolerance, runs make_valid for topology cleanup, and stamps each polygon with {fire_id, acquisition_dt, burn_pct, area_m2}. NaN inputs are excluded (not thresholded as < threshold). The op preserves the input CRS -- if the CRS is geographic and simplify_meters > 0, a warning is emitted (no silent reprojection).
