refactor: 删除冗余 cli 入口脚本, gittool 用数组配置 clean excludes

1. 删除 13 个已有 YAML 配置的 cli .py 入口脚本, 统一通过 pf 调用
2. gittool.yaml 用 CLEAN_EXCLUDES 数组变量配置 git clean 的 -e 参数,
   保留 .venv/.tox/node_modules/.idea 等目录避免误删
3. run_cli 执行前打印调用信息: [gittool] 执行: c
4. 更新 pyproject.toml 移除 13 个冗余 entry points, 仅保留 pf
5. 清理测试文件中的 TestMain 类 (测 _ops 模块的测试保留)
