fix(desktop): recover outdated managed host storage at startup

[M4n5ter]

English

Summary

• Fix Desktop startup after upgrading while a managed Local Runtime Host still uses an older storage schema at the same protocol epoch. Previously, Work Board initialization failed outside startup recovery.
• Check shared local storage before admitting the candidate; close a rejected connection and use the existing managed update/restart flow. Desktop never performs the migration.
• Preserve manual-update and active-task interruption consent. Unsupported newer schemas and unrelated storage failures do not authorize automatic repair. Remote peers and the protocol epoch are unchanged.

Verification

• Regression test uses a real SQLite usage-v6 table: Desktop leaves it unchanged, releases the old connection before repair, and becomes ready after the simulated updated owning Host migrates it. Retained usage identity survives.
• Desktop full suite: 2,317 passed, including the startup recovery regression and real UDS integration. Storage full suite: 1,125 passed, 10 skipped.
• Full build, typecheck, lint, formatting, renderer architecture, ASF headers and Desktop/UI dependency checks passed.
• The reported macOS managed service still needs an on-device retry with this branch; no live Mac data was changed during testing.

AI use

• Generative tooling made a substantive contribution

Tool(s) and scope: Codex — implementation and tests.

Checklist

• Tests cover the change and fail without it
• Lint, format, typecheck and the affected suites pass locally

Summary

• 修复升级 Desktop 后，旧 managed Local Runtime Host 协议 epoch 相同、存储 schema 却落后而导致无法启动的问题。此前 Work Board 的初始化错误落在启动恢复流程之外。
• 在接纳本地连接之前检查共享存储，失败时关闭该连接，进入已有的 managed 更新/重启流程。迁移始终由 Host 执行。
• 保留手动更新和中断活跃任务的确认；不把更高版本数据库或其它存储故障当作自动修复许可。不修改远程连接或协议 epoch。

Verification

• 使用真实 SQLite usage-v6 表做回归：Desktop 不修改旧表，先释放连接，再由模拟的新 owning Host 迁移并恢复启动；保留原有 usage 身份记录。
• Desktop 全量 2,317 项通过，含启动恢复回归及真实 UDS 集成。Storage 全量：1,125 项通过、10 项跳过。
• 全量构建、类型、lint、格式、renderer 架构、ASF 头及 Desktop/UI 依赖检查通过。
• 尚需在报告问题的 Mac 上拉取此分支验证 managed 服务升级；测试未修改 Mac 实际数据。
