✨ feat(vscode): 代码阅读的注释挂到它讲的代码块上成「注释」一行，重写注释改用技能一句话加结构化结果

- 普通注释不再单独成卡片：同一层挂到后面最近的块（隔空行也算），后面没有挂到前面那块，整层没代码挂到父块；只有文件开头隔着空行的注释、模块 docstring、//!、@file 单独成「文件开头的说明」
- 各语言（Python、TypeScript、Rust、Shell、Dockerfile）建好树后统一调 attachComments；块的编辑范围连着挂上的注释，差异、跳转、钉住卡片都按它
- 宿主统一给每张卡片（语言卡片、翻译插件的属性表、库规则卡片、一行译文的语句卡片）插「注释」一行，排在名称、说明后面
- TypeScript 的 JSDoc 也能当常量、变量的说明；sqlx、React 不再单独处理前面的注释
- 「重写注释」每块都有：提示只发 /ecc:writing-code-comments 路径:起-止，模型只读、按 --json-schema 交 body，没交结构化正文就失败不写；扩展换掉块前面的注释或在块上面新写一段
