feat: add rename infrastructure

This prepares us for a future rename:

* It tries to load a receipt named "dist", in case this is a post-upgrade release;
* If we load a "cargo-dist" receipt, it sets the internal name to "dist" to ensure
  that we look for the next release under the correct name.

This shouldn't be merged until we know this is going to be the last pre-rename release.
