feat(android): 可选 Shizuku 与三层跨应用粘贴回退 (#932)
* feat(android): add optional Shizuku accessibility recovery path
Integrate best-effort OpenLessAccessibilityService recovery via Shizuku UserService with safe rollback, manifest/Gradle scaffolding, JNI bridge, settings UI, and contract tests.

* fix(android): add primary constructor for Shizuku UserService Stub
Kotlin requires an explicit supertype initializer when extending AIDL Stub; fixes Gradle compile error on CI.

* fix(android): replace accessibility heartbeat with IPC paste results
Remove SharedPreferences cross-process heartbeat gating, use structured PASTE/PING IPC with safe retry rules, tighten editable target validation, and fix Shizuku manifest attribute merging for mixed-quote providers.

* fix(android): use literal const values in accessibility command receiver
Kotlin const val cannot reference enum codes; fixes release APK compile.

* fix(android): 修复无障碍组件短名与全名匹配误判
Settings.Secure 常以 pkg/.Class 存储服务列表，主检测路径改用 ComponentName 规范化比较，避免 enabled=false 误报未授权；同步 Rust JNI 路径并补齐测试。

* fix(android): 为 JNI 调用的无障碍检测方法添加 @Keep
Release 构建中 R8 会剥离仅由 JNI 反射调用的 pingAccessibilityProcess，导致 NoSuchMethodError 与 operational=false 误报；同步保护 isEnabled 并补充契约测试。

* fix(android): 恢复无障碍粘贴的可编辑目标回退查找
粘贴失败日志为 NO_FOCUSED_EDITOR：过严的 isFocused 校验与移除树遍历导致找不到输入框。恢复 FOCUS_ACCESSIBILITY、宽松焦点匹配与 findEditableInTree 回退，并保留严格缓存校验。

* fix(android): 跨窗口扫描与缓存优先修复粘贴目标查找
微信等场景下 rootInActiveWindow 非输入窗口导致 NO_FOCUSED_EDITOR；改为缓存优先、遍历全部无障碍窗口，并加深树搜索。

* fix(android): 识别非 isEditable 的粘贴目标节点
微信等 App 不向无障碍暴露 isEditable；扩展为 EditText/ACTION_PASTE/ACTION_SET_TEXT 目标，并订阅文本变更事件以预热缓存。

* fix(android): 三层粘贴回退（无障碍 → Shizuku → 剪贴板）
无障碍失败后尝试 Shizuku 注入 KEYCODE_PASTE，再回退剪贴板；精简 Tier1 为 findFocus + ACTION_PASTE。
Co-authored-by: Cursor <cursoragent@cursor.com>
* fix(android): 粘贴结果校验与 Shizuku processNameSuffix
ACTION_PASTE 返回 true 但文本未写入时降级为 PASTE_REJECTED 并走 Tier2；修复 UserService 绑定 NPE；Tier1 成功后跳过 Shizuku。

* fix(android): 恢复无障碍可编辑目标查找以修复微信等应用粘贴
aaa3fbf2 将 Tier1 简化为 findFocus 导致微信等应用 PASTE_REJECTED；恢复跨窗口/树扫描与焦点缓存，保留粘贴结果校验与 Promise.allSettled 容错。

* fix(android): 通过 IPC 传递粘贴文本修复后台剪贴板读取被拒绝
无障碍子进程在应用未聚焦时无法读剪贴板，导致 Tier1 直接 PASTE_REJECTED；主进程将听写文本经 EXTRA_PASTE_TEXT 传入粘贴流程。

* fix(android): Tier2 粘贴改用 Shizuku.newProcess 绕过 MTK UserService 崩溃
联发科/小米 ROM 上 UserService 进程在 LoadedApk.makeApplicationInner 因 procName 为 null 而 NPE；粘贴键注入优先走 Shizuku.newProcess，失败再回退 UserService。
Co-authored-by: Cursor <cursoragent@cursor.com>
* fix(android): Tier2 粘贴改用 Shizuku daemon UserService
newProcess 为私有 API；粘贴键注入改走 daemon(true) 绑定，避免 MTK 上 :shizuku 子进程 Application NPE。
Co-authored-by: Cursor <cursoragent@cursor.com>
* test(android): 修正 daemon 粘贴契约断言
Co-authored-by: Cursor <cursoragent@cursor.com>
* fix(android): daemon 粘贴绑定补全 processNameSuffix
Shizuku UserServiceArgs 要求 suffix 非空；daemon(true)+suffix=paste 避免此前 null NPE 与 MTK :shizuku 子进程崩溃。
Co-authored-by: Cursor <cursoragent@cursor.com>
* fix(android): Tier2 粘贴经反射调用 Shizuku.newProcess
MTK 上 UserService 子进程仍触发 LoadedApk NPE；粘贴键注入优先反射 newProcess 执行 input keyevent 279，UserService 作回退。

* chore(android): 移除粘贴调试日志
微信等应用三层粘贴回退已在真机验证通过，清理 DBG-21a66f/DBG-53a00d 临时 instrumentation。
Co-authored-by: Cursor <cursoragent@cursor.com>
* fix(android): 修复 CI 单元测试在无 Robolectric 下失败
ComponentIds 改为纯 Kotlin 规范化（对齐 Rust）；isValidServiceComponent 拒绝首尾空白；Target 测试改用 action id 常量。
