feat: 算法升级、整车配准集成与性能分析文档

算法更新: delivery v1.2.1、平整度v1.5、测距v2.2、整车配准v1.3
适配器: vehicle-registration 新增、各算法 manifest 和 adapter 更新
后端: taskCadFiles/source 字段迁移、derivedPointClouds 注册、取消任务联动
前端: ElapsedTime 时长显示、两步算法流程、canRun 逻辑修复
文档: 新增5份算法性能分析报告

+`__version__` tracks the package release; bump on any user-visible change.
+`ALGORITHM_VERSION` tracks the deflection algorithm itself; bump whenever
+internal computation changes in a way that may shift numeric results.
+`SCHEMA_VERSION` tracks the structure of `DeflectionResult.to_dict()` /
+`report.json`; bump on any field rename, removal, or semantic change.
+Adding new optional fields is a non-breaking change and does NOT require a
