fix: PlayerBar进度条边框线移除及按钮居中修复，release构建优化

- 移除PlayerBar顶部border线，进度条紧贴边缘无需分隔线
- 减少推荐按钮改为absolute定位，不参与播放控制按钮居中计算
- 删除未使用的npm依赖(howler/axios/@vueuse/motion/@vicons/ionicons5)
- @iconify-json/lucide移至devDependencies
- Cargo.toml添加[profile.release]优化(strip/lto/codegen-units/panic/opt-level)
- crate-type精简，移除不需要的staticlib
- Vite构建优化(esnext目标/CSS合并/vendor chunk拆分)
