feat: sync upstream pi-mono (386 commits)

从上游 badlogic/pi-mono 同步 386 个提交，手动解决所有冲突：

保留 SproutClaw 独有功能：
- RPC: reload 命令、bash 流式输出、get_extensions 命令
- settings-manager: showChangelogOnStartup 设置
- agent-session: turnIndex getter
- 移除 pi 版本检查通知（interactive-mode）
- skills 系统、启动脚本、自定义工具脚本

直接采用上游版本：
- packages/ai 模型列表及测试文件
- packages/coding-agent 文档
- 其余未冲突的全部上游代码

升级 @mistralai/mistralai 至 2.2.6（修复 promptCacheKey 类型错误）
