windows-latest intermittently kills an entire test file's child process: the runner reports `✖ <file> ... 'test failed'` with a non-zero exit, no failing assertion and no diagnostics. It lands on a different heavyweight example suite each run (smart-cockpit gateway composition, AI Passport device relay), fails the same way on main, and never reproduced in ~120 targeted reruns on windows-latest / Node 24.15.0 (3 shards x [15 smart-cockpit groups + 15 AI Passport groups + 10 composition runs] plus three full `npm test` runs). Retry `npm test` once on Windows only and announce the retry as a warning annotation, so a flaky pass stays visible in the job instead of hiding a real regression. Two failed attempts still fail the job; other platforms keep the single-run behaviour.

感谢针对 Windows 偶发测试进程退出提供缓解方案，也感谢此前详细的复现调查。维护者评估后，暂不采用当前对所有 npm test 失败统一重试的策略：实现尚未区分已知进程退出与真实测试失败，可能掩盖间歇性回归。我们会优先评估后续诊断日志方案，保留故障现场后再决定是否需要有针对性的重试，因此先关闭本 PR。感谢理解和贡献！ |

Summary
npm testbehavior behind a Windows-only single retryThis addresses the CI mitigation requested in #413. It does not claim to fix the underlying Windows child-process failure; it keeps the failure visible while avoiding unrelated intermittent red jobs.
