test(runtime-host): investigate owned candidate connection flake #3190
Description
English
Summary
The Runtime Host test owned Host exits promptly after its first connection closes flakes under the full CI suite.
In CI run 32101082229, test_runtime_host completed 962 of 963 tests and failed at owned-candidate.test.ts:66:
- expected:
connected - actual:
failed - configured election deadline: 2 seconds
PR #3188 does not change Runtime Host code or its test inputs, so this is not attributable to that PR.
Impact
Unrelated pull requests can receive a blocking red CI result without a product regression.
Suggested investigation
Preserve the concrete failure reason in this test before asserting the result kind, then determine whether the two-second election deadline or candidate readiness path is timing-sensitive under full-suite CI load.

摘要
Runtime Host 测试 owned Host exits promptly after its first connection closes 在完整 CI 套件中出现不稳定失败。
在 CI run 32101082229 中，test_runtime_host 的 963 项测试通过了 962 项，最终在 owned-candidate.test.ts:66 失败：
- 预期：
connected - 实际：
failed - election deadline：2 秒
PR #3188 没有修改 Runtime Host 代码或测试输入，因此该失败并非由该 PR 引入。
影响
无关 PR 可能在没有产品回归时收到阻塞性的红色 CI。
建议调查方向
在断言 result kind 前保留具体 failure reason，再判断两秒 election deadline 或 candidate readiness 路径是否会在完整 CI 负载下产生时序问题。
AI 使用说明以英文区为准。
