feat: v1.1 P1 功能实现 + 体验优化（4 项新功能 + 9 项修复）

Browse Source 
## 新功能

### 视频时长放宽（Feature 5）
- LivePhotoCore: targetDuration 从固定 0.917 秒改为动态计算（0.5-5.0 秒）
- LivePhotoCore: keyFrameTime 按比例映射到目标视频时长
- EditorView: slider 上限从 1.5 秒提升至 5.0 秒
- EditorView: 超过 2 秒显示壁纸兼容性提示，超过 3 秒显示分享截断提示

### 自定义封面帧（Feature 4）
- ExportParams: 新增 coverImageURL 字段
- EditorView: 封面帧区域增加 PhotosPicker 从相册导入照片作为封面
- AppState: coverImageURL 传递到 LivePhotoWorkflow
- EditorView: onDisappear 时清理临时封面文件，避免磁盘泄漏

### 收藏/模板预设（Feature 6）
- 新增 PresetManager.swift: EditingPreset 模型 + 预设管理器
- 支持保存/加载/删除预设，最多 10 个
- UserDefaults + iCloud KV Store 双重持久化
- EditorView: 预设保存/加载 UI + 空状态 ContentUnavailableView

### iCloud 同步（Feature 7）
- RecentWorksManager: 新增 NSUbiquitousKeyValueStore 同步
- PresetManager: 同步支持 iCloud KV Store
- 合并策略：按 ID 去重，保留最新记录，限制条数上限

## Bug 修复

### P0 级
- ResultView: Live Photo 预览比例从固定值改为动态计算 aspectRatio
- EditorView: 修复本地化字符串拼接问题（使用 String(localized:) 替代硬编码）

### P1 级
- EditorView: 预设列表空状态显示 ContentUnavailableView
- ProcessingView: 进度环与百分比文本动画同步（统一 overallProgress 计算）

### P2 级
- EditorView: 添加触觉反馈（比例切换、生成按钮、预设保存、封面导入）
- HomeView: 删除作品触觉反馈 + 入场动画优化
- ProcessingView: 脉冲动画背景尺寸微调（160-175pt）
- LaunchScreen: 品牌启动画面（App Icon + 标题 + 副标题）

## 本地化

- 新增约 25 个本地化 key，覆盖 8 种语言
  （zh-Hans, zh-Hant, en, ja, ko, es, fr, ar）
- 包含：预设管理、封面导入、时长提示、删除确认、
  空状态、诊断建议等全部新增 UI 文案
