Bug Fixes:

• Retry ZeroMQ send, receive, and poll operations when they fail with EINTR instead of treating them as hard errors.

Hey - 我在这里给出了一些总体反馈：

• retry_on_eintr 辅助函数在遇到反复出现的 EINTR 时会无限循环；建议增加一个最大重试次数或超时参数，以避免在病态场景下出现无界的忙等循环。
• 为了一致性和可读性，你可能希望让 poll_item 也使用 retry_on_eintr（或类似的循环），而不是在遇到 EINTR 时特判并返回 false，这样可以在 send/recv/poll 操作之间统一 EINTR 的处理语义。

给 AI Agent 的提示

Please address the comments from this code review:

## Overall Comments
- The `retry_on_eintr` helper loops indefinitely on repeated `EINTR`; consider adding a maximum retry count or timeout parameter so a pathological scenario doesn’t cause an unbounded tight loop.
- For consistency and clarity, you might want `poll_item` to also use `retry_on_eintr` (or a similar loop) rather than special-casing EINTR with a `false` return, so EINTR handling semantics are uniform across send/recv/poll operations.
