feat: v0.8.0 流语义补全 · 会话可靠 · 恢复力 — finish_reason 全链路贯通根治"思考中停止" · 2445 用例全量回归

/**
|

* v0.8.0 P2-1: 会话回收站（软删除 30 天保留）回归测试。
|
||||
*
|
||||
* 钉住契约：
|
||||
* - delete → 软删除（deleted_at 时间戳），list/getSession 不再返回，listDeleted 返回；
|
||||
* - restore → 恢复到主列表；
|
||||
* - purge → 硬删除（不可恢复）；
|
||||
* - purgeExpiredTrash(30d) → 仅清理超期条目；
|
||||
* - searchMessages 聚合剔除回收站会话。
|
||||
*
|
||||
* 运行要求：better-sqlite3 为 Electron ABI 构建（test:electron），系统 Node 下自动跳过。
