IDEA - RAW+JPEG pairing with shared rating / flag / label

First off: if this is already possible and I've just overlooked a setting, sorry for the noise, and I'd appreciate a pointer on how to enable it.

Summary

I'd like RapidRAW to treat a RAW file and its matching JPEG as a single logical image. Lightroom calls this stacking ("Auto-Stack by RAW+JPEG"), darktable calls it grouping.

Right now, "Prefer RAW" (#527) only hides the JPEG from view. It doesn't link the two files, so each keeps its own independent .rrdata sidecar. A rating, flag, or label set on the RAW does not apply to its paired JPEG.

The problem

For anyone shooting RAW+JPEG (safety copy, or a camera with no RAW-only mode), culling on the RAW leaves the matching JPEGs untouched:

• Rating a RAW 1-star (reject) does nothing to its JPEG.
• A rating-based cull or cleanup misses the JPEGs entirely.
• You end up with orphan JPEGs to hunt down and delete manually.

"Prefer RAW" fixes the display clutter, but not the culling problem.

Desired behavior

1. Files sharing a basename in the same folder (e.g. IMG_0123.RAW + IMG_0123.JPG) are auto-detected as a pair.
2. The pair shows as a single library entry, with a small badge indicating it's a pair, so no duplicate thumbnails.
3. Ratings, flags, and color labels apply to the whole pair. Reject the RAW and the JPEG is rejected too, so a rating-based cull catches both files.
4. A preference to choose the primary member (RAW by default), i.e. which one is displayed and edited.
5. Optional: an "expand pair" action to see and select the individual files.
6. Optional: a per-pair delete that removes both files at once.

On feasibility

The hard part, detecting RAW/JPEG pairs by basename, already exists since "Prefer RAW" (#527) relies on it. So this is really about extending that existing pair detection to also share metadata.

Thanks for the great work on RapidRAW.
