fix(concurrency): nonisolated(unsafe) static shared + 修同 actor 内冗余 await
项目开启了 -default-isolation=MainActor upcoming feature,导致:
1. static let shared 默认被视为 MainActor 隔离,即使 class 标了
@unchecked Sendable,从其他 actor(如 AIRuntime)同步访问仍报
"Expression is 'async' but is not marked with 'await'".
修法:ModelStore.shared 和 FileVault.shared 都加 nonisolated(unsafe)
修饰,明确"任何隔离上下文都可同步访问"。
2. AIRuntime.generate() 内的 Task { ... } 继承 AIRuntime actor 隔离,
self.recordRate 是同 actor 内部调用,不需要 await,否则报
"No 'async' operations occur within 'await' expression".
修法:去掉冗余的 await。
** BUILD SUCCEEDED ** 已验证。
