v0.8.1 — 定时队列止损与可观测性

0.8.1

修复 / 调度：

• #32 同点批量定时任务：持久 FIFO 队列现提供排队深度、最久等待时间和最大并发数；进行中卡片显示排队数，可打开队列查看正在等待派发的任务，并可二次确认清空任务队列。清空只移除尚未派发的队列项，已运行会话不受影响。
• 新增可选的队列保质期（queueMaxAgeMinutes，默认 0，继续保留跨重启补跑）与定时会话启动间隔（dispatchIntervalMs，默认 1000 ms；可显式设为 0 关闭节流）。
• 调度器以单飞 tick 和全局派发闸门避免 interval/catchup 重叠时并行放行队列。
• 移除 DSH STORE 的客户端产物大小预算与专用测试；仍保留客户端压缩作为常规构建优化，而非发布门槛。

Fixes / Scheduling:

• #32 concurrent scheduled tasks: the durable FIFO queue now exposes its depth, oldest wait, and concurrency cap; the in-progress card shows the queued count, and users can open the queue to inspect waiting tasks or double-confirm clearing it. Clearing only removes entries that have not been dispatched; running sessions are unaffected.
• Adds optional queue shelf life (queueMaxAgeMinutes, default 0, retaining restart replay) and scheduled-session start spacing (dispatchIntervalMs, default 1000 ms; set it explicitly to 0 to disable throttling).
• The scheduler uses a single-flight tick and global dispatch gate to prevent interval/catchup overlap from releasing queued work in parallel.
• Removes the DSH STORE client-artifact size budget and its dedicated test. Client minification remains a normal build optimization, not a release gate.
