修复: workspace_root 编译期常量消除+data_dir 运行期+首次授权引导

- 删除 production 中全部 env!("CARGO_MANIFEST_DIR")引用
- workspace_root() 替换为运行期 data_dir(Tauri app_data_dir)
- 相对路径锚定改为 AllowedDirs.first_persistent_dir()，无授权时引导绑定项目
- .trash 迁到 data_dir/.trash，含自动迁移
- authz_debug → temp_dir，workspace_drive → current_dir
- run_command 默认 working_dir 改为空串
- G1 目标刷新改为每次消息覆盖(含 ai_chat_edit 路径)
- #6 评分关键词拆到独立文件 scoring_keywords.rs
- #7 promote 补偿删除 purge_with_descendants → soft_delete
- #8 关联双向同步: 后端事务 sync_related_ids + IPC + 前端全链路
- 设置面板新增数据目录显示
