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

/resume のリモートセッション復元フローと、Missing field timestamp を報告する遷移から始め、バージョン 1.0.79 と 1.0.81 の動作を比較してください。可能であれば失敗を再現し、その後、リモートセッションがローカルに復元され、失敗時に /diagnose 用の診断情報が残ることを確認してください。
