refactor(bf-bot): 插件重构为 handlers/services/utils 分层，资源归入 res/
- 旧平铺模块（data/data_utils/database_op/image_builder*/get_bf6_data/ gametools_bf6/bf6_data/img_utils）拆分为 handlers（绑定/查询）、 services（fetchers/processing/query）、utils（渲染/参数）分层； 新增 repository.py / config.py / paths.py - 字体/图片/模板资源迁入 res/，新增 BF2042 卡面素材（bg/object_icon 等） - browser_ext/：BF2042 扩展捕获桥（WS 直连兜底通道）源码入库 - 新增 hexi/web/src/plugins/bf_bot 前端管理页 - 新增 tests：test_bf_bot_helpers / repository / tracker_api Co-Authored-By: Claude Code <noreply@anthropic.com>

// HeXi BF2042 捕获桥 - Service Worker
|
||||
//
|
||||
// 两个职责:
|
||||
// 1) 持有到本机 bot 的 WebSocket(自动重连 + 心跳),转发页面捕获的响应;
|
||||
// 2) 执行 bot 下发的取数任务:找/开 tracker.gg 标签页 → 首页 bootstrap →
|
||||
// 站内跳转进 profile 页 → 等页面自己发出 XHR → 上报 job_done。
|
||||
//
|
||||
// 导航定律(来自插件文档,勿改):地址栏深链会被 Cloudflare 挑战,必须先落首页、
|
||||
// 再在站内跳转。全程不用任何调试端口,浏览器就是个普通实例。
|
||||
//
|
||||
// 重试机制:页面撞 CF 挑战/403 时,页面自己的 XHR 不会产出数据,本轮
|
||||
// ATTEMPT_WAIT_MS 内关键响应收不齐 → 自动重走"首页→站内跳转"(刷新等价),
