课表行新增 Schedule.source（manual / classisland）：插件每次全量上报时，服务端 只清理「source=classisland 且本次未再上报」的行。原先 merge 只做 upsert，老师在 ClassIsland 里删掉或挪走一节，服务端会永远留着那行幽灵课；现在能真正同步下来， 而老师在小助手这边手排的课（manual）一律不删。 配套改动： - 插件上报时带回 machineKey，服务端回填到设备记录（避开 [classId, deviceKey] 唯一约束）； - 新增迁移 20260930120000_add_schedule_source，存量数据保守地按 manual 处理； - verify:classisland 补「幽灵行清理」「手排课不被误删」用例。 另：.gitignore 补上 .zcode/ 与 .zcodeignore（AI 会话产物，不属于产品代码）。
