feat: ranked top-3 queen candidates with probability shown - honest AI, user verifies

feat: binary classifier cascade - prefers dedicated queen classifier, falls back to VLM grid

feat: VLM cascade for queen verification (YOLO finds candidates, Qwen-VL confirms via grid comparison)

feat: ship combined-dataset YOLO weights (Matt Nudi + Hendricks; queen mAP 0.99 + better generalization)

polish: remove emojis and em dashes from sources and docs

polish: seed sample hives, polished CSS theme, rich About + README, dataset live on Hub

feat: class aliasing + varroa support, ready for hendricks_ricky weights

fix: per-class confidence thresholds, queen-only label, mites clearly marked as VLM estimate

feat: SQLite hive registry + inspection history tab, persistent across sessions

wire moondream2 (placeholder VLM) + add iNaturalist scraper + data sources doc
