实现 type: ping checker，通过 Bun.spawn 调用系统 ping 命令，自行实现跨平台 输出解析器（Linux/macOS/Windows 含中文 locale），支持 alive、丢包率、延迟、 耗时等 expect 断言，复用现有 checker 架构零外部依赖。 包含完整的类型定义、TypeBox schema、语义校验、命令构建、解析、断言、执行、 注册、配置加载测试，以及 probe-config.schema.json 更新和文档更新。 审查修复：提取 buildPingCommand 为独立纯函数并补充跨平台单测，补充 maxDurationMs/maxAvgLatencyMs 类型非法和空字符串 host 边界测试用例。 变更已归档，delta specs 已同步至 main specs。
