feat(windows): WebView2 lazy webviews + Android auto-update + history repolish

[HKLHaoBin]

User description

Summary

• Windows (WebView2 memory): Lazy-create auxiliary webviews (QA, less-computer, glow) and destroy them on dismiss; add QaStateSnapshot for cold-start hydrate; lazy-load FloatingShell tabs and Settings sections to shrink main-window first paint and idle renderer count.
• Android auto-update: Background check/download with stable/beta channels, settings UI alignment, updater logic extraction + unit tests, CI release signing on dispatch when keystore secrets exist, and fixes for launch-time JNI crashes (Build.SUPPORTED_ABIS, accessibility state, ProGuard @Keep on bridge methods).
• History ([area:style] 润色结果偶发与原文完全一致，缺少重试提示 #653): Opt-in polish-unchanged detection, history-level repolish IPC/UI (excluding translation history), and preserve insert error codes on retry.
• Dictation: Compute done_message before moving error_code into session (fixes a move-after-use bug).

Test plan

• Windows: cold start — confirm main window loads; open/close QA panel, glow, less-computer; verify auxiliary webviews are created on demand and memory drops after dismiss
• Windows: QA panel re-open after dismiss — state hydrates via snapshot
• Android: launch app — no crash ~4s after start (updater background check)
• Android: auto-update settings — stable/beta toggle, manual check, download + install flow
• Android: overlay recording still works after foreground-service changes
• History: enable polish-unchanged detection; verify repolish retry on unchanged polish; translation history excluded
• Dictation: error paths still emit correct done message

PR Reviewer Guide 🔍

Here are some key observations to aid the review process:

🎫 Ticket compliance analysis 🔶 653 - Partially compliant Compliant requirements: 润色未变化检测：添加了 is_polish_unchanged 和 normalize_for_polish_compare 函数，在 end_session 中调用 resolve_polish_unchanged_error_code 生成 polishUnchanged 错误码。 用户反馈：done_message 中返回中文提示“本次润色未产生变化，可在历史中重新润色”；历史详情页展示黄色提示条。 历史记录标识：列表中添加 polishUnchanged Pill 标签；详情页显示提示块。 重新润色操作：历史详情页提供「重新润色」按钮（触发 repolish_history_entry IPC），复用原 raw_transcript，无需重新录音。 功能默认关闭（polish_unchanged_enabled: false），用户可在设置中开启。 Non-compliant requirements: （无） Requires further human verification: （无）
