feat: 模块统一 ias- 前缀、独立版本与内网地址支持 (0.1.7)
- 所有 Rust crate 统一加 ias- 前缀：ai → ias-ai、common → ias-common、context → ias-context、mail → ias-mail、service → ias-service、wechat → ias-wechat - 新增 ias-main 模块承载 CLI 入口和二进制打包 - 各模块开始独立维护版本号，ias-main 0.1.7 代表整体版本 - 新增 IA_WEB_INTERNAL_URL 环境变量，版本通知同时发送公网和内网链接 - 将已有升级日志翻译为中文 - ias_upgrade_logs 新增 modules JSONB 字段 - 新增 VERSION 文件和 CHANGELOG.md - 新增 AGENTS.md 项目规则文件
