Fix restoring cloud conversation transcripts

[seemeroland]

Description

Fix cloud conversation transcript viewer pane getting permanently stuck in the loading state after quit and restart.

When a pane was viewing a cloud conversation transcript (from an ambient agent run), the pane is saved as an AmbientAgent snapshot. On restore, it creates a loading pane and defers restoration until task data arrives from the server. The deferred handler calls fetch_and_load_transcript, which used a two-step lookup: first find_conversation_id_by_server_token to map the server token to a local AIConversationId, then load_conversation_data. If the conversation's metadata wasn't included in the initial cloud metadata fetch (e.g., 3 requested but only 2 returned), the token was never found locally. The task was re-inserted into the pending restorations map, but no further events fired to retry — leaving the pane stuck in Loading forever.

The fix switches fetch_and_load_transcript to use load_conversation_by_server_token, which already has a built-in server fallback when the token isn't in the local cache.

Testing

• Quit Warp while a pane is viewing a cloud conversation transcript

• Restart Warp

• Verify the pane loads the conversation transcript instead of staying in the loading spinner

• I have manually tested my changes locally with ./script/run
