refactor(toolchain)!: 工具链 plugindev 更名为 hmapdev，module path 改回 gitcode

- 目录 tools/plugindev → tools/hmapdev，可执行文件名/平台产物名同步
  （hmapdev_linux_amd64 等；包格式仍叫 .hmap）
- module path github.com/JianFeeeee/homeagent-sdk/tools/... → gitcode.com/...
  （与仓库实际托管一致；核心仓不依赖该 path，改动无外部影响）
- SDK 存储目录 ~/.homeagent/plugindev/sdk → ~/.homeagent/hmapdev/sdk
  新目录不存在而旧目录存在时沿用旧目录 → 已装 SDK 版本不会丢失
- 命令表/usage/--help/生成项目 README/示例 README/NSIS 安装器/
  package/build.sh/build-examples.sh 全部同步；PLUGINDEV 环境变量保留兼容
- sdk/ 目录零改动（公开接口不变）

验证：
- go build ./... ok；go test ./tools/hmapdev/ ok（含模板接线守卫 TestProcTemplate_CoversAllCoreMethods）
- bash -n package/{build,build-examples}.sh ok
- 端到端：hmapdev init demo && hmapdev build → dist/demo_bundle.hmap（linux+darwin）
- 本机安装 /usr/local/bin/hmapdev，旧名以软链保留；sdk list/current 正常

 - The kernel also cleans up on uninstall: tool registrations, the `disabled_plugins` record, the plugin's config definitions (`plugin.<name>.*`) and its config table (`config_<name>`) — the plugin's config section disappears completely after removal.
