Lataa Data Maskit 0.11.2

更新摘要 / Summary
- 更新弹窗和「关于」页现在直接告诉你这次改了什么，不再只有一句「修复 2 项」或一整段技术日志。
- Windows 桌面版不会再出现「点了启动却起不来」：端口探测多了一条兜底，不再单靠系统命令。
- 启动失败时不再只有一句「未就绪」：端口被占用、旧引擎残留、令牌没写出来会分开说明，日志也不会再因为进程被杀而整片丢失。
- The update card and About page now tell you what actually changed, instead of a bare count or a wall of technical text.
- Windows desktop no longer fails to start: port detection has a fallback when the system command reports nothing.
- A failed start now says why — port taken, stuck engine, or missing token — and engine logs survive a force-kill.
修复
- Windows 启动：端口探测不再只依赖系统命令，命令被拦截或超时返空时改用连接探测兜底。此前该命令一旦失灵，就绪判定永远认为端口未监听，点启动会等满 60 秒后报失败，常驻守护还会反复重启正常工作的代理。
- 引擎日志：壳层强杀引擎时，engine-stdout.log 的块缓冲来不及 flush，内存里的诊断行随进程一起消失（引擎存活期间该文件恒为空）。现由壳层注入 PYTHONUNBUFFERED，并把 [panel] / [engine] / [proxy] 诊断行落盘到数据目录 engine.log（2MB 轮转）；SHIELD 事件行携带原文预览，仍然只进内存。
- 引擎启动：守护线程的假死判定（6 轮 × 2s ≈ 12s）比就绪预算（20s）更早，会把正在初始化的引擎强杀重拉，慢机上表现为「永远起不来 / 反复重启」；现加与就绪预算同值的启动宽限。就绪超时也不再只报一句「未就绪」：区分端口被第三方进程 / 本产品残留引擎占用、系统查不到占用 PID、令牌未写出，并把启动失败现场补写进 crash-dumps。
优化
- 版本说明：更新弹窗与「关于」页只展示「更新摘要」，不再把整章 CHANGELOG（含 ### 标记与双语技术条目）原样渲染给用户；桌面端 latest.json 的 notes 也从「修复 N 项」改为摘要正文。
- 版本说明：新增 scripts/check-changelog.py 门禁（已进 scripts/verify-all.py 的 version 组与 ci.yml），强制每个版本章节开头有中英双语「更新摘要」，并拦截反引号、源码文件名、文件：行号、4xx/5xx 状态码与硬技术术语。历史版本（0.10.1 之前）不回溯。
Fixed
- Windows start: port detection no longer relies solely on the system command; when it is blocked or returns nothing, a connection probe takes over. A failing command previously made the readiness check see no listeners forever — start waited the full 60 s and reported failure, and the resident watchdog kept restarting a healthy proxy.
- Engine log: a force-killed engine never got to flush its block-buffered stdout, so engine-stdout.log stayed empty for the engine's whole lifetime and every diagnostic line died with the process. The shell now injects PYTHONUNBUFFERED and persists [panel] / [engine] / [proxy] lines to engine.log in the data directory (2 MB rotation); SHIELD event lines carry plaintext previews and stay in memory only.
- Engine start: the watchdog's hang detection (6 rounds × 2 s ≈ 12 s) fired before the 20 s readiness budget and killed engines that were still initialising, which on slow machines looked like "never starts / restarts forever"; a start grace period now matches the readiness budget. A readiness timeout also reports why (port held by a third-party process, a stuck engine of ours, an unidentifiable listener, or a token that was never written) and dumps the failure scene into crash-dumps.
Improvements
- Update notes: the update card and About page now render only the user-facing summary instead of the whole CHANGELOG section (raw ### markers and bilingual technical entries); the desktop latest.json notes carry the summary body instead of an "N fixed" count.
- Update notes: new scripts/check-changelog.py gate (added to scripts/verify-all.py's version group and ci.yml) requires a bilingual summary section at the top of every version section and rejects backticks, source filenames, file:line refs, 4xx/5xx status codes and hard jargon. Versions before 0.10.1 are exempt.
