- agentcli 平台无关化：plugin.go 拆为公共层 + ptyTerm 接口，新增 pty_linux.go（/dev/ptmx 原实现搬移，行为不变）与 pty_windows.go （ConPTY 原生实现，CreatePseudoConsole + PROC_THREAD_ATTRIBUTE_PSEUDOCONSOLE 注入子进程，双管道读写/ResizePseudoConsole/GetExitCodeProcess，零第三方依赖） - plugin_stub.go 收紧为 !linux && !windows（darwin 等仍走桩） - plugin_test.go build tag 放宽到 linux || windows - cabi/loader.c 补 linux || darwin build tag，修复 Windows 下 cgo 禁用时残留 C 源文件的编译错误 - 验证：Linux 全量构建+测试通过；Windows CGO 交叉编译 + go vet 全包零错误
