3.5.0 - 2026-08-09

Added cooperative-work and memory-pressure policies shared by DOCX, PPTX,
and XLSX, including foreground preemption, adaptive batch sizing, bounded
concurrency, and critical-pressure preload shutdown.
Added privacy-safe responsiveness diagnostics for maximum work slice, long
tasks, yields, background preemptions, memory pressure, and the separately
identified uninterruptible DOCX third-party render phase.
Added a three-process extended large-file gate for 500-page DOCX,
2,000-slide PPTX, an Excel-row-limit sparse workbook, and a
50,000-row/400,000-cell dense workbook. Scheduled and release workflows
retain machine-readable results, trend points, and Markdown summaries.

DOCX visible DOM is now committed with adaptive batches and browser yields;
memory and DOM pressure reduce each batch without changing document order.
PPTX metadata indexing now prioritizes slides around the current page,
yields after bounded batches, and lets foreground slide rendering preempt
background indexing and thumbnail preload. Critical pressure stops preload.
XLSX worksheet streams now apply serialized backpressure, parse bounded XML
slices, and yield between slices. Critical pressure drops inactive worksheet,
shared-string, and image caches before more work is scheduled.
Fast CI keeps the 100-page/1,000-slide/100,000-row/80,000-cell fixtures,
while both performance tiers enforce a 50 ms maximum cooperative work slice,
output consistency, cancellation, cleanup, heap, DOM, cache, and bundle gates.

Dense worksheet decompression can no longer enqueue overlapping parser work;
stream events are serialized before resume, preserving XML order under
cooperative yielding and rapid cancellation.

增加 DOCX、PPTX、XLSX 共用的协作任务与内存压力策略，覆盖前台抢占、
自适应批次、有界并发和临界压力下停止预加载。
增加隐私安全的响应性诊断：最大工作切片、长任务、让出次数、后台抢占、
内存压力，以及单独标记的 DOCX 第三方不可中断渲染阶段。
增加三次独立进程的扩展大文件门禁，覆盖 500 页 DOCX、2,000 页 PPTX、
Excel 行上限稀疏工作簿和 50,000 行/400,000 单元格稠密工作簿；定时与发布
工作流保留机器可读结果、趋势点和 Markdown 摘要。

DOCX 可见 DOM 改为自适应批次提交并主动让出浏览器；内存和 DOM 压力会
缩小批次，但不改变文档顺序。
PPTX 元数据索引优先处理当前页附近幻灯片，并在有界批次后让出；前台幻灯片
渲染可抢占后台索引与缩略图预加载，达到临界压力时停止预加载。
XLSX 工作表流增加串行背压，以有界 XML 片段解析并在片段间让出；临界压力
下会先释放非活动工作表、共享字符串和图片缓存，再调度后续工作。
快速 CI 继续使用 100 页/1,000 页/100,000 行/80,000 单元格样本；两级性能
门禁同时验证 50 ms 最大协作切片、输出一致性、取消、清理、堆、DOM、缓存
和包体积。
