fix(runtime-host): preserve legacy handoff operator

[M4n5ter]

English

Summary

Preserve the only operator artifact guaranteed by a released schema-1 Local Runtime Host handoff when Desktop adopts an already-active managed authority. The recovered schema-2 receipt now points to the existing POSIX operator, while schema-2 setup recovery continues to use the portable Node operator.mjs.

This keeps adoption read-only with respect to the managed deployment: recovery does not replay setup, change the exact package, or mutate lifecycle ownership.

Refs #4657

Root cause

The operator-command migration converted a released handoff to schema 2 before choosing its operator representation. That erased the fact that the handoff came from a release which only guaranteed <deploymentRoot>/operator, allowing recovery to persist a receipt for an operator.mjs that had never been converged.

Verification

• Desktop main TypeScript build
• Biome on the two changed files
• Local Runtime Host remote-access recovery tests: 14/14 passed
• git diff --check

摘要

Desktop 在接管已经 active 的 managed authority 时，为已发布的 schema-1 Local Runtime Host handoff 保留该版本唯一保证存在的 operator artifact。恢复后的 schema-2 receipt 现在指向既有 POSIX operator；schema-2 setup recovery 仍使用 portable Node operator.mjs。

接管过程不会修改 managed deployment：恢复时不重放 setup、不切换 exact package，也不改变 lifecycle ownership。

关联 #4657

根因

operator-command 迁移在选择 operator representation 之前先把已发布 handoff 转成了 schema 2，丢失了“该 handoff 所属版本只保证 <deploymentRoot>/operator”这一事实，因此可能持久化一个从未 converge 的 operator.mjs receipt。

验证

• Desktop main TypeScript build
• 对两个变更文件执行 Biome
• Local Runtime Host remote-access recovery 测试：14/14 通过
• git diff --check
