Unable to restore remote session locally

Describe the bug

I'm trying to restore a remote session locally. I run /resume and select the session:

Then I get an error:

● Resuming task locally (1s)
└─ Loading remote session
└ ○ Validating repository
└ ○ Checking for uncommitted changes
└ ○ Fetching and checking out branch
└ ○ Creating local session from remote events
└ ○ Saving session to disk

Error: Missing field timestamp
esc to return to session picker

I tried to use /diagnose to diagnose, but it found no missing timestamps (nothing was recorded for the failure).

Affected version

1.0.79 and 1.0.81

Steps to reproduce the behavior

No response

Expected behavior

Remote sessions should restore; failures should be debuggable.

Additional context

No response

从 /resume 远程会话恢复流程以及报告 Missing field timestamp 的转换开始；比较 1.0.79 和 1.0.81 版本中的行为。如果可能，复现该故障，然后验证远程会话能够在本地恢复，并且故障会为 /diagnose 留下诊断信息。
