Different releases incorrectly considered duplicate

### Problem

I'm trying to import both https://musicbrainz.org/release/3e475b92-6217-43cf-8557-e0c11bc96091 and https://musicbrainz.org/release/0701e066-6823-4987-946e-ad04a972bb0c but when I try to import the second one it is considered duplicate. Catalog number is different and they have different tracks, but I'm not allowed to have both albums in my library.

### Setup

* OS: void-linux
* Python version: 3.12.3
* beets version: 1.6.0
* Turning off plugins made problem go away (yes/no): no (even worse, now autotagger can't even match the release!)

My configuration (output of `beet config`) is:

```yaml

Reproduce the import using the two MusicBrainz release URLs with the supplied beets configuration, then isolate whether the duplicate decision changes when plugins are disabled. Trace the duplicate check and autotagger result for these releases; done means both releases can be imported separately while existing duplicate detection still works.
