v3.5.0 在线视频下载登场，AI 翻译更可靠

feat

• 全新「视频下载」功能：粘贴链接即可下载 B 站、YouTube 等平台的在线视频，yt-dlp 与 lux 双引擎，下载完成一键进入字幕任务
  New "Video Download" feature: paste a link to grab videos from Bilibili, YouTube and more with dual yt-dlp / lux engines, then hand off to subtitle tasks in one click
• 下载时自动获取平台官方字幕并在任务向导中自动配对，有官方字幕就无需再转写
  Official subtitles are fetched during download and auto-paired in the task wizard — no transcription needed when official subs exist
• 支持导入站点 Cookie（浏览器一键提取 / cookies.txt / 手动粘贴），解锁登录后才可见的高清画质与会员内容
  Import site cookies (browser extraction, cookies.txt, or paste) to unlock login-gated resolutions and member-only content
• 新增全局 AI 翻译术语表：多词库管理、优先级排序、CSV/TXT 导入导出，命中的术语自动注入翻译提示词，专有名词翻译更统一 (#287) (感谢 @nightt5879 #354)
  New global AI translation glossaries: manage multiple glossaries with priority ordering and CSV/TXT import/export; matched terms are auto-injected into prompts for consistent terminology (#287) (thanks @nightt5879 #354)

• AI 服务商新增「思考模式」开关：默认关闭思考让翻译更快更省，需要深度推理时可随时打开

  New unified storage root: one setting now manages all model directories and temp files — no more changing paths one by one (#388)

  Fixed a crash at transcription start with ultra-long audio (9h+): long content is now split at silences and merged back seamlessly
