fix(examples): 全插件安全审查修复(qq/a2a/memo/calendar/rss/browser/bili/recoverydiag)
审查发现并修复 7 项问题: - P1 qq: downloadURL 裸 http.Get 无超时 → 120s client - P2 a2a: inbound http.Server 零超时 → Read 30s/Write 120s/Idle 60s - P3 bili: output_dir 配置项零校验 → 系统目录黑名单(/、/etc、/usr、/var 等) - P4 recoverydiag: db_path LLM 可控任意 sqlite → 强制限制 data 目录内 - P5 memo/calendar/rss: os.WriteFile 直写 → atomicWriteJSON (temp+rename) - P6 qq: 3 处后台 goroutine(已读/rcon转发/下载)加 panic recover - P7 browser: dump-dom failback Kill 后补 wait 回收僵尸进程 recoverydiag 此前被 .gitignore 排除,但其 db_path 安全修复 属生产代码,故取消忽略并入库。 全部经 plugindev 重打包升版安装验证 config_kept=true。
