feat(core): services.yaml 启动配置 + _run.sh 统一参数透传

Step 1: init.txt → services.yaml
- 新增 InitParser (yaml-cpp), 支持 YAML/TXT 双模式解析, 向后兼容 init.txt
- 新增 services.yaml 声明式服务配置 (name/cmd/args/depends_on/sleep_before)
- 改造 pmc_mtd.cpp 集成 InitParser, 支持目录/.yaml/.txt 三种路径模式
- Makefile 添加 InitParser 编译目标 + -lyaml-cpp 链接
- setup 脚本添加 libyaml-cpp-dev / yaml-cpp-devel 依赖
- core/_run.sh 改为 -i . (目录模式, 自动查找 services.yaml → init.txt)

Step 2: 11 个 _run.sh 统一参数透传
- 8 个脚本改动: 追加 "$@" / 移除 sleep / 修引号
- waf 保留 -c config.yaml 作为脚本默认值
- services.yaml waf args 改为 [] 避免重复传递
- 开发方案文档: docs/reports/core_services_yaml_dev_doc.md
