Hide the target annotation only when main is the sole recorded target. Keep it visible alongside other targets after a PR is retargeted.

Duplicate of #1218?

Duplicate of #1218?

Yes, same fix. This one here also updates the test expectations and covers repeated runs targeting only main. I left out (target: none) because the aggregator always records a branch or unknown, so an empty list isn't reachable.
