详细修改内容： - 新增disableAiAudio配置项，用于屏蔽AI增强音质 - 重构音质获取逻辑，支持自动降级可用音质 - 优化Android端播放上下文同步流程 - 移动端播放器新增音质快速选择弹窗 - 修复音质切换失败后的回滚逻辑 - 调整预加载策略，优化切歌体验 - 优化播放错误处理逻辑
- 新增无权限歌曲过滤机制，无权限时自动跳过曲目 - 新增 Android 端音频 URL 本地缓存，切歌时优先命中已缓存资源 - 新增 isPromotedAudioReady 接口，检测预载音频是否已完整缓存 - 优化 syncApiContext 调用顺序，确保上下文同步后再并发请求 - 优化 AudioPrefetchTtlIndex 清理逻辑，避免未过期条目被误删 - 优化 sweep 使用 peekSimpleCache 替代 getOrCreate，避免不必要的缓存初始化 - 优化 getPromotedAudioFile 使用 getOrCreate 保证缓存实例可用 - 播放无权限歌曲时给出明确提示并自动跳至下一首 - syncApiContext 去重键新增 playSongDemo 维度

📌 变更类型
📝 变更说明
本 PR 主要修复 Android 原生播放在后台 / 锁屏场景下的在线歌曲 URL 解析、预载和自动切歌稳定性问题，并优化高音质播放的缓存预热策略。
核心改动：
disableAiAudio与 Android 原生播放上下文同步逻辑，确保音质开关变化后 Java 端能拿到一致的音质过滤与降级策略。apiBaseUrl / cookie / songLevel，避免updateQueueContext先到达导致 URL 解析跳过。512KB提升到2MB，降低音频在开头数秒跨过缓存边界后发生阻塞的概率。🔗 关联 Issue
