格式化工具在展开单行语句时引入了 5 处语法错误，导致 dx serve 无法编译：
- comments.rs / trash.rs：on_select 的 `if checked { insert } else { remove }`
丢失 else 分支，变为悬空语句 + 括号不匹配。
- trash.rs（3 处）：`web_sys::window().and_then(|w| {...}).unwrap_or(false) {`
展开闭包体时漏掉闭合 `)`，吞掉了 if 块的开括号。
- write.rs：封面图 `if cv.contains('?') {...} else {...}` 丢失 else，
多出一个 `}`，导致 src 块括号失衡。
均还原为正确的多行 if/else 结构。验证：dx check 通过、cargo test 405 passed。
