feat: 路径配置化 + 裸二进制启动 + pluginmgr 内置插件

- types.go: 新增 PluginDirConfig 结构体嵌入 Config
- config/registry.go: 新增7个路径配置项 (core.plugin.dir 等) + ConfigDef 元数据
- cmd/homed/main.go: -data 默认自动检测二进制同级目录，使用 cfg.Plugin.Dir
- internal/plugins/pluginmgr/: 内置插件实现 (4工具 + HTTP API + 包校验)
- all.go: 注册 pluginmgr
- manifest.go: 扩展 PluginManifest 字段
- sdk/settings.go: RegisterDef / Defs 接口
- webui: 设置页自动发现 ConfigDef 元数据
- config/config.go, config/config.yaml: 清理 YAML 死代码
- sdk/plugin.go: IO 通道泛型化支持非文本类型
- waiter: CLI 支持 socket 发现和交互模式
