fix(inbound): keep polling while turns are active

中文说明

这个 PR 修复了 Weixin 长轮询被当前 Agent 回合阻塞的问题。此前 monitor 会等待整条消息处理完成，导致回合运行期间的新消息和 /approve plugin: 无法及时进入 OpenClaw Core。现在每次轮询保存游标后立即继续拉取；普通消息按顺序送入 Core，并在被接收或排队后释放通道，/approve plugin: 则使用独立通道避免被普通回合阻塞。队列、steer、follow-up 和审批鉴权/执行仍由 Core 负责。

Summary

• Keep the Weixin long-poll loop running while OpenClaw processes an active turn.
• Preserve ordinary-message preprocessing order until core accepts or queues each turn.
• Give only /approve plugin: an independent admission lane so approvals are not blocked by an active ordinary turn.
• Preserve quoted approval command parsing and queued-followup progress lifecycle handling.
• Leave queue, steer, follow-up, approval authorization, and resolution to OpenClaw core.

Scope

This is a single focused commit changing three files. It adds no dependency, configuration, persistence layer, host version gate, or OpenClaw core change.

Validation

• Focused compatibility/monitor/inbound/command/progress tests: 56/56
• Typecheck: pass
• Build: pass
• Package dry-run: 116 files
• Full suite: 394/398; the four failures match the existing Windows baseline (one path-separator assertion and three first-import timeouts)
• Live Weixin validation: active-turn steering and plugin approval handling completed successfully on OpenClaw 2026.7.1-beta.6

目前 block了 approval 和 steer 两个基本场景

[NewFuture]

The behavior implemented by this PR has been released in the current community-maintained openclaw-weixin v3.0.1 through the community implementation 10bf058:

https://github.com/NewFuture/openclaw-weixin

The released implementation keeps long polling active after OpenClaw admits/queues a turn, preserves ordinary-message admission order, and gives /approve plugin: an independent lane so approval messages are not blocked by an active ordinary turn. Queueing, steering, follow-ups, authorization, and approval resolution remain owned by OpenClaw core.

One-line in-place replacement/upgrade (requires OpenClaw >=2026.6.1; do not uninstall the official package first):

openclaw plugins install npm:openclaw-weixin --force

The plugin/channel ID and state paths are unchanged, so this normally preserves existing configuration and login state.

For clarity: the linked repository/package is a community-maintained distribution, not the official Tencent/Weixin release. This upstream Tencent PR remains open; this comment records an equivalent released community implementation rather than claiming a Tencent-side merge.
