Back the code generator's Vue 3 template migration: col_width lets R2's column-width inference be overridden per field, and default_value lets R1/A6's "unconfigured rows still generate a usable page" guarantee hold for generated forms. Both use a sentinel default (0 / "") rather than NULL so "unconfigured" has exactly one representation - see docs-prd/010-代码生成器前端模板迁移Vue3/数据库变更.md §1.1. The migration and the model change land together: AddColumn reads the column definition off tools.SysColumns's own gorm tag, so splitting them across commits would leave one of them failing to compile.
