feat: EH Downloader 用 Go + Wails v2 重写

原 Electron 版在这台 Windows 机器上无法启动（0x80000003 崩在 V8 初始化），整个业务逻辑用 Go 重写，前端界面与协议结论完全保留。 - internal/eh: 协议核心，画廊页分页 -> /s/ -> hath 直链 -> 下载 - internal/core: 并发引擎 / 状态存储 / 目录模板 / 油猴桥口 - app.go: Wails 绑定层，替代 Electron IPC - frontend/js/api.js: 适配层，renderer.js 一行未改 - 37 个测试，含 httptest 模拟 EH 的端到端链路验证相比 Electron 版：90MB -> 12.4MB，180MB 内存 -> 27MB，构建 90s -> 2s。顺带修掉原版代理探测的 bug（永远返回第一个端口，从不等连接结果）。
