fix(scripts): backfill_group_members 窗口函数化过 MySQL only_full_group_by(单库收敛)

max(timestamp)+裸 sender_name 的 GROUP BY 是 SQLite 方言行为,MySQL 8 默认
only_full_group_by 直接 1055 拒绝——2026-08-27 单库收敛(本地+调度器同连
Docker MySQL)时在 MySQL 上实跑触发。改 row_number() OVER 取每 (room_id,
talker_id) 最新一行的 sender_name + count() OVER 计数:两库通用,且语义从
「碰巧取 max 行」变为严格最新一条。另 gitignore 补 *.db.retired
(smoke.db 退役改名后 *.db 规则罩不住)。
