新增 places365_categories.json (380 個場景類別) - 更新場景識別使用 Places365 類別名稱 - 使用最常見場景類型作為影片主要場景 - 改進場景合併邏輯 改進: - 場景名稱從 'unknown_X' 改為實際場景索引 - 支援 Places365 380 個場景類別 - 自動統計最常見場景類型 限制: - ResNet18 使用 ImageNet 1000 類別 - Places365 只有 365 類別，索引不完全匹配 - 建議使用專門的 Places365 模型獲得最佳結果 測試結果: - ExaSAN 影片識別為 scene_664 (37% 信心度) - 處理時間：1.3 秒 - 79 個取樣點成功處理 --- scripts/places365_categories.json | 382
