实现 Issue #29: Modbus/CoAP/HTTP 协议适配器 + AdapterFactory 工厂

功能实现：
- 创建 IDeviceAdapter 统一接口
- 实现 Modbus TCP 和 Modbus RTU 协议适配器
- 实现 CoAP 协议适配器（基于 Eclipse Californium）
- 实现 HTTP 协议适配器（基于 Apache HttpClient）
- 实现 AdapterFactory 工厂类，支持自动协议识别
- 添加数据验证、类型转换、批量操作等功能
- 创建配置文件和使用示例
- 添加单元测试

技术特点：
- 工厂模式 + 策略模式设计
- 支持多种协议：Modbus TCP/RTU、CoAP、HTTP/HTTPS
- 自动协议检测和适配器选择
- 完整的数据模型和验证机制
- 针对智慧水务领域优化

协议支持：
- modbus-rtu: Modbus RTU协议（串口）
- modbus-tcp: Modbus TCP协议（网络）
- coap: CoAP协议（物联网）
- http/https: HTTP协议
- 支持动态协议注册

文件变更：
- 新增 20+ Java 类文件
- 新增配置文件和测试代码
- 实现完整的水务设备适配功能

+# @gar/promisify
+
+### Promisify an entire object or class instance
+
+This module leverages es6 Proxy and Reflect to promisify every function in an
+object or class instance.
+
+It assumes the callback that the function is expecting is the last
+parameter, and that it is an error-first callback with only one value,
+i.e. `(err, value) => ...`. This mirrors node's `util.promisify` method.
+
+In order that you can use it as a one-stop-shop for all your promisify
+needs, you can also pass it a function.  That function will be
+promisified as normal using node's built-in `util.promisify` method.
+
+[node's custom promisified
+functions](https://nodejs.org/api/util.html#util_custom_promisified_functions)
+will also be mirrored, further allowing this to be a drop-in replacement
+for the built-in `util.promisify`.
+
+### Examples
+
+Promisify an entire object
+
+```javascript
+
+const promisify = require('@gar/promisify')
+
+class Foo {
+  constructor (attr) {
+    this.attr = attr
+  }
+
+  double (input, cb) {
+    cb(null, input * 2)
+  }
+
+const foo = new Foo('baz')
+const promisified = promisify(foo)
+
+console.log(promisified.attr)
+console.log(await promisified.double(1024))
+```
+
+Promisify a function
+
+```javascript
+
+const promisify = require('@gar/promisify')
+
+function foo (a, cb) {
+  if (a !== 'bad') {
+    return cb(null, 'ok')
+  }
+  return cb('not ok')
+}
+
+const promisified = promisify(foo)
+
+// This will resolve to 'ok'
+promisified('good')
+
+// this will reject
+promisified('bad')
+```

+# @npmcli/fs
+
+polyfills, and extensions, of the core `fs` module.
+
+## Features
+
+- all exposed functions return promises
+- `fs.rm` polyfill for node versions < 14.14.0
+- `fs.mkdir` polyfill adding support for the `recursive` and `force` options in node versions < 10.12.0
+- `fs.copyFile` extended to accept an `owner` option
+- `fs.mkdir` extended to accept an `owner` option
+- `fs.mkdtemp` extended to accept an `owner` option
+- `fs.writeFile` extended to accept an `owner` option
+- `fs.withTempDir` added
+- `fs.cp` polyfill for node < 16.7.0
+
+## The `owner` option
+
+The `copyFile`, `mkdir`, `mkdtemp`, `writeFile`, and `withTempDir` functions
+all accept a new `owner` property in their options. It can be used in two ways:
+
+- `{ owner: { uid: 100, gid: 100 } }` - set the `uid` and `gid` explicitly
+- `{ owner: 100 }` - use one value, will set both `uid` and `gid` the same
+
+The special string `'inherit'` may be passed instead of a number, which will
+cause this module to automatically determine the correct `uid` and/or `gid`
+from the nearest existing parent directory of the target.
+
+## `fs.withTempDir(root, fn, options) -> Promise`
+
+### Parameters
+
+- `root`: the directory in which to create the temporary directory
+- `fn`: a function that will be called with the path to the temporary directory
+- `options`
+  - `tmpPrefix`: a prefix to be used in the generated directory name
+
+### Usage
+
+The `withTempDir` function creates a temporary directory, runs the provided
+function (`fn`), then removes the temporary directory and resolves or rejects
+based on the result of `fn`.
+
+```js
+const fs = require('@npmcli/fs')
+const os = require('os')
+
+// this function will be called with the full path to the temporary directory
+// it is called with `await` behind the scenes, so can be async if desired.
+const myFunction = async (tempPath) => {
+  return 'done!'
+}
+
+const main = async () => {
+  const result = await fs.withTempDir(os.tmpdir(), myFunction)
+  // result === 'done!'
+}
+
+main()
+```

+# @npmcli/move-file
+
+A fork of [move-file](https://github.com/sindresorhus/move-file) with
+compatibility with all node 10.x versions.
+
+> Move a file (or directory)
+
+The built-in
+[`fs.rename()`](https://nodejs.org/api/fs.html#fs_fs_rename_oldpath_newpath_callback)
+is just a JavaScript wrapper for the C `rename(2)` function, which doesn't
+support moving files across partitions or devices. This module is what you
+would have expected `fs.rename()` to be.
+
+## Highlights
+
+- Promise API.
+- Supports moving a file across partitions and devices.
+- Optionally prevent overwriting an existing file.
+- Creates non-existent destination directories for you.
+- Support for Node versions that lack built-in recursive `fs.mkdir()`
+- Automatically recurses when source is a directory.
+
+## Install
+
+```
+$ npm install @npmcli/move-file
+```
+
+## Usage
+
+```js
+const moveFile = require('@npmcli/move-file');
+
+(async () => {
+	await moveFile('source/unicorn.png', 'destination/unicorn.png');
+	console.log('The file has been moved');
+})();
+```
+
+## API
+
+### moveFile(source, destination, options?)
+
+Returns a `Promise` that resolves when the file has been moved.
+
+### moveFile.sync(source, destination, options?)
+
+#### source
+
+Type: `string`
+
+File, or directory, you want to move.
+
+#### destination
+
+Type: `string`
+
+Where you want the file or directory moved.
+
+#### options
+
+Type: `object`
+
+##### overwrite
+
+Type: `boolean`\
+Default: `true`
+
+Overwrite existing destination file(s).
