feat(selection-voice): Windows 选区语音编辑 MVP，划词提问面板预览与意图分流 (#987) (#995)

* feat(selection-voice): Windows 选区语音编辑 MVP（issue #987）

选区 + 专用快捷键 + 语音指令：指令润色后按 auto/manual/heuristic 分流到 QA 或 EditPlan 确定性编辑，含设置页、预览窗与热键集成。

* fix(selection-voice): 修复 Windows 编译（展平 session 模块结构）

Co-authored-by: Cursor <cursoragent@cursor.com>

* fix(selection-voice): 用 polish_text 替代 ActiveLLMProvider::complete

Co-authored-by: Cursor <cursoragent@cursor.com>

* fix(ci): 补全 mock trait 与 SessionId 单元测试类型

Co-authored-by: Cursor <cursoragent@cursor.com>

* fix(release): feature 分支跳过 MSI 并上传 NSIS 安装包

Co-authored-by: Cursor <cursoragent@cursor.com>

* fix(selection-voice): post-utterance intent picker and merged settings

Let users choose question vs edit after speaking (default prompt mode), merge polish and voice into one settings card, keep hotkey supervisor polling, and show capsule errors when trigger preconditions fail.

Co-authored-by: Cursor <cursoragent@cursor.com>

* fix(i18n): add selectionWorkspace keys for ja, ko, zh-TW

Co-authored-by: Cursor <cursoragent@cursor.com>

* fix(selection-voice): compare hotkey supervisor signatures as Option<&str>

Co-authored-by: Cursor <cursoragent@cursor.com>

* fix(coordinator): gate selection_voice_intent_prompt init to Windows

Co-authored-by: Cursor <cursoragent@cursor.com>

* fix(selection-workspace): unify voice and polish hotkey with edge prefetch

Reuse the selection polish shortcut for voice edit and prefetch selection at hotkey press to avoid Alt clearing the selection before capture.

Co-authored-by: Cursor <cursoragent@cursor.com>

* fix(selection-voice): align auto/toggle hotkey modes and intent UX

Match dictation auto short/long-press semantics, fix toggle stop blocked by busy flag, block overlapping dictation, and invert intent toggle to heuristic-off / AI-on.

Co-authored-by: Cursor <cursoragent@cursor.com>

* fix(ci): gate selection-voice dictation block to Windows only

selection_voice_session is Windows-gated; non-Windows builds failed with E0433 when dictation referenced it unconditionally.

Co-authored-by: Cursor <cursoragent@cursor.com>

* fix(selection-voice): surface end-workflow errors instead of stuck loading

When stopping a voice session, failures during ASR, intent, or edit-plan steps now reset state and show a user-facing capsule error with stage hints.

Co-authored-by: Cursor <cursoragent@cursor.com>

* fix(selection-voice): annotate end-workflow async block error type as String

Windows CI failed because the async block inferred Result<_, str> instead of Result<_, String>.

Co-authored-by: Cursor <cursoragent@cursor.com>

* fix(selection-voice): route translation edits through translate pipeline

Infer target language from voice instructions like translate-to-English and build a full_rewrite plan via translate_text instead of fragile EditPlan JSON. Also normalize common LLM JSON aliases and improve parse fallbacks.

Co-authored-by: Cursor <cursoragent@cursor.com>

* feat(selection-voice): use XML EditPlan format for LLM edit responses

Switch voice-edit system prompt to XML envelopes with child elements for multiline text. Add parse_edit_plan with XML-first parsing and JSON fallback for legacy outputs.

Co-authored-by: Cursor <cursoragent@cursor.com>

* fix(edit-plan): correct XML entity match string literals

Fix E0762 unterminated character literal in decode_xml_text that broke all platform builds.

Co-authored-by: Cursor <cursoragent@cursor.com>

* fix(edit-plan): resolve XML parser type errors for CI

Use Option for find_open_tag, fix unwrap_or types, bool attr matching, and promote_alias_field slice arity.

Co-authored-by: Cursor <cursoragent@cursor.com>

* fix(edit-plan): fix remaining XML parser compile errors

Co-authored-by: Cursor <cursoragent@cursor.com>

* fix(edit-plan): fix tuple arity, map remove keys, and borrow in normalize

Co-authored-by: Cursor <cursoragent@cursor.com>

* fix(selection-voice): unify voice edit with QA panel and improve intent

Route voice edits through QaPanel for shared preview/confirm UX, hide capsule when the session ends, prioritize heuristic edit cues for auto intent, and fix translation identity checks.

Co-authored-by: Cursor <cursoragent@cursor.com>

* feat(selection-voice): 统一语音编辑为 QA 面板预览模式并支持回退

将选区语音编辑流程统一到 QA 面板，新增预览与回退功能。

- 新增 `revert_selection_voice_preview` Tauri 命令及 IPC 调用，支持回退到上一轮编辑预览
- 在 QA 面板中新增 `editRevertAvailable` 状态，处理预览模式下的错误与空闲状态
- 优化 `emit_selection_voice_end_error` 逻辑：预览模式下错误回退到 Idle 状态并关闭面板，其他模式下显示错误胶囊
- 新增翻译结果与原文相同时的错误提示
- 跟踪 `previous_preview_text` 以支持回退操作
- 同步更新多语言（zh-CN、zh-TW、en、ja、ko）编辑按钮文案及新增回退文案

* fix(ci): gate selection-voice QA follow-up to Windows and fix compile errors

Add missing selection_voice_preview_mode helper, cfg-gate revert command registration, and release QA mutex before async follow-up edit to satisfy Send.

Co-authored-by: Cursor <cursoragent@cursor.com>

* fix(ci): stub selection module in backend-tests harness

hotkey.rs now prefetches workspace selection on polish shortcut; provide no-op stub for Rust-only test crate.

Co-authored-by: Cursor <cursoragent@cursor.com>

* feat(qa): route intent by interrogative and add edit-instruction mode

Detect question vs non-question for selection-voice Auto intent, polish QA mic ASR, and gate ask/edit on the panel checkbox so text and voice stay consistent.

Co-authored-by: Cursor <cursoragent@cursor.com>

* feat(selection-voice): 增强语音编辑功能，优化 QA 面板状态同步

* fix(selection-voice): stop legacy edit keywords from misrouting to QA

Filter pre-#987 default keywords like 「改成」 so edit imperatives no longer match question heuristics, and reset qa_stream_cancelled before streaming so prior QA cancellations do not yield empty-stream failures.

Co-authored-by: Cursor <cursoragent@cursor.com>

* fix(selection-voice): address review blockers

* fix(selection-voice): gate QA preview cleanup to Windows
