## Message

```
Add VecMap::entry_ref (#52601)

Thinking more on #52596, I realized the `entry` method needs a key by
value, which meant we were always cloning a path list even if it was
already in the map. This PR adds an `entry_ref` that takes the key by
reference and delays cloning the key until we know we're going to be
inserting.
