Subject: [PATCH] =?UTF-8?q?fix(ai,persistence):=20ModelStore=20+=20FileVau?=
 =?UTF-8?q?lt=20=E6=A0=87=20@unchecked=20Sendable?=

Xcode 26 默认开启 Swift 6 严格并发检查。AIRuntime(actor)
调用 ModelStore.shared.isReady(...) 跨 actor 边界,因 ModelStore
非 Sendable 而编译报错"Expression is 'async' but is not marked
with 'await'; this is an error in the Swift 6 language mode"。

两个类的内部状态只读(rootURL: let),方法只做线程安全的
filesystem I/O,符合 Sendable 语义,标 @unchecked Sendable
即可,不必加锁或重构。

修复目标错误:
- AIRuntime.swift:48 - guard ModelStore.shared.isReady(.llm) ...
- 后续 CaptureService 调 FileVault.shared.writeJPEG 同样路径

不影响:
- HomeView/B5ResultView 里 Text "+" 的 macOS 26.0 deprecation 是
  warning,不阻塞 build,留待 UI polish 周清理
