The pick option creates an allowlist for the merged EXIF output, which drops latitude/longitude even when gps:true is set. Fixed by calling exifr.gps() as a separate step (bypasses the pick filter entirely). Also adds a startup backfill that re-extracts GPS for already-indexed photos where gps_lat IS NULL, including reverse geocoding for place names.
