Git index slow to update

All published crates have been synced to the Git index, and there is now no backlog.

57 pending syncs.

Now at 116 pending syncs. Probably 1½ hours before we're caught up, give or take.

The queue burndown has slowed due to an unusual number of crate publishes in the last hour, but it is slowly making progress and is now at 206 pending syncs. It could be anywhere from 2-4 hours from here until it catches up.

Due to a large number of crate versions being published in the last few hours, the legacy Git crate index is currently approximately 245 crate versions (or about two hours) behind.

The sparse index (which has been the default since Rust 1.70, released in June 2023) is unaffected.
