* chore: 删除临时规划文档 wx_channel.md 并还原 package.json 排序

wx_channel.md 内容已整合到 docs/features/channels.md，不再需要。
package.json 中 @ant/model-provider 位置从原始位置被无意移动，还原。

* refactor: 将 weixin 模块从 src/ 迁移至 packages/weixin 工作区包

将 src/services/weixin/ 中的纯业务逻辑迁入 @claude-code-best/weixin
workspace 包，降低 src/ 耦合度。仅保留 server.ts 作为薄适配层。

- 迁移 7 个无修改的纯模块 (types/api/accounts/login/pairing/media/send)
- monitor.ts 内联 PERMISSION_REPLY_RE 正则，解除对 src/ 的依赖
- permissions.ts 本地定义 ChannelPermissionRequestParams 接口
- cli.ts 拆分：serve 子命令通过回调注入，login/access 保留在包内
- server.ts 重写为从 @claude-code-best/weixin 导入
- 新增 cli-serve.ts 作为 serve 入口薄壳

* fix: 修正 weixin barrel export 中 interface 的导出方式

ChannelPermissionRequestParams 是纯类型，必须用 export type 导出，
否则 Bun 运行时会报 "export not found" 错误。

* refactor: 将 server.ts 迁入 packages/weixin，彻底移除 src/services/weixin/

通过依赖注入（WeixinServerDeps）解耦 src/ 依赖（analytics、config、
MCP channel schema），server.ts 完全移入包内。cli.tsx 入口处一次性
注入所有依赖。

src/services/weixin/ 目录已完全删除。

* fix: 修复 markdownToPlainText 中代码块正则的 ReDoS 风险

用非正则的线性扫描替代 \`\`\`[\s\S]*?\n([\s\S]*?)\`\`\` 匹配，
避免在含有大量重复 \`\`\` 序列的输入上触发多项式回溯。
