- 修复 #37：Linux 下 df 遇到 FUSE 挂载点（如 /run/user/1000/doc）权限不足 时不再整体失败，只要 stdout 有有效数据即正常返回其余磁盘信息 - 解决 #39：CPUConfig 新增 excludeIowait 选项（默认 false 保持现有行为）， 设为 true 时从 overall 使用率中剔除 iowait，适合 I/O 密集型场景 - 补充对应单元测试（linux-adapter: 4 个，cpu-monitor: 4 个） - 同步更新 README.md 与 README-zh.md Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

Background
Linux 桌面环境（GNOME/KDE）中，
/run/user/1000/doc等 FUSE虚拟挂载点在非 root 权限下会导致
df命令以 exit code 1退出，进而使磁盘监控功能整体失败（#37）。
CPU 使用率在 I/O 密集型场景下存在虚高问题：iowait 期间 CPU
实际处于空闲状态，但被计入 overall 使用率，与
top等工具的展示口径不一致（#39）。
Key Changes
LinuxAdapter.getDiskInfo()/getDiskUsage()：当df有有效 stdout 输出时，不再强依赖 exit code 为
0，权限错误仅影响对应挂载点，不阻断整体磁盘数据返回
CPUConfig新增excludeIowait?: boolean（默认false），CPUMonitor.transformCPUUsage()在该选项启用时从overall中减去iowait，iowait字段本身不受影响src/adapters/linux-adapter.ts、src/monitors/c pu-monitor.ts、src/types/config.tsdf容错逻辑仅在 stdout 行数 ≥ 2时生效，完全失败场景仍正常抛出
MonitorError，无回归风险Test Matrix
npm run buildnpm run test:unitnpm run test:linux / windows(if applicable)npm run lint:checkRelated Issues
Platform & Permissions
df权限容错仅对 Linux 生效，macOS / Windows 不涉及excludeIowait仅在 Linux 采样数据中有意义（macOS / Windows适配器不返回 iowait 字段，设置后无副作用）
Documentation
README.md/README-zh.md：全局配置示例补充excludeIowait，CPU 监控器章节新增配置项说明表格及代码示例Additional Notes
excludeIowait默认false，完全向后兼容，现有用户无需任何改动配额），该问题复杂度较高，建议单独排期
