- 删除 cache_manager/audio_proxy/device_key_pool 中 21 处 cacheMutex：database/sql 连接池本身并发安全，SQLite 已配 WAL + busy_timeout，PostgreSQL 无并发写限制 - contentRequestCount 三函数由互斥锁改为 atomic.Int64 - cache_manager 中 config.GetConfig() 改为 GetAppConfig()，消除配置未初始化时 log.Fatal 崩溃整个进程的隐患 - VACUUM 与写操作的低频并发冲突由 busy_timeout 兜底（已注释说明） - 新增 TestConcurrentCacheAccess：8 goroutine 并发读写缓存，-race 验证无死锁无竞争
