feat: 原始线索面板加下载按钮

popup 的「原始线索」面板顶部加下载按钮,跟复制按钮并列。没有选具体技术(rawSourceContext 为空)时下载完整 raw JSON,选了某条技术的「原始线索」按钮后下载 scoped JSON(只含该技术相关的源)。文件名格式 `stackprism_<host>_[tech]_[source]_<ISO 时间戳>.json`,自动从当前页面 URL 拿 hostname,去掉非法路径字符。同时把 scoped raw 默认带上响应头字段(之前只有「响应头」来源才包含),方便 spoof 场景下交叉对照伪造头与具体识别项。

将版本号提升到 1.3.59。
