feat: v0.3.0 - 流式播放、本地音乐、下载系统、漫游修复

### 新功能
- 流式播放：边下载边播放，缓冲 64KB 后即刻开始，无需等待完整下载
- 本地音乐页面：支持浏览、播放本地歌曲，横向菜单含「从磁盘删除」
- 下载系统：支持下载歌曲到自定义路径，保存完整元数据（封面/专辑/时长）
- 封面补全：本地音乐缺少封面时自动从网易云 API 获取
- 更新信息：接入 Gitea Releases API，查看最新版更新日志

### 修复
- 修复私人漫游播完一首歌后跳三首的问题（双重触发：audio-ended + startTick）
- 修复全屏漫游抽屉和漫游页面无封面歌曲显示破损图片
- 修复 PlayerBar 无封面歌曲显示破损图片
- 修复下载路径修改后不生效（Rust serde camelCase 映射）
- 修复本地音乐始终只显示默认路径歌曲
- 修复下载完成提示弹出 4 次
- 修复播放网络歌曲时进度条先走但无声音（audio-started 事件同步）

### 优化
- PlayerBar 下载状态：未下载显示下载按钮，下载中显示进度，已下载不显示
- audio.rs 新增 manual_stop 标志防止 stop_audio 触发虚假 audio-ended
- player.ts 新增 waitForAudioStart() 确保 playing 状态与实际播放同步
- 切歌/停止时立即清除 tickInterval 防止重复触发 next()
