`primed-stage-packages` in `manifest.yaml` loses architecture information
Metadata
Current evaluation
primed-stage-packages in manifest.yaml drops foreign-arch qualifiers (e.g. :i386) while stage-packages keeps them. Root cause is in craft-parts origin tracking; a craft-parts PR (#1558) has since fixed it.
Suggested action: keep open
Reason: A maintainer (gcomneno) triaged this on 2026-03-21 and identified the root cause as cross-repo: craft-parts' origin tracking uses `dpkg-deb --show --showformat=${Package}=${Version}`, dropping the `:i386`/`:armhf` qualifier. A craft-parts commit (0b6a556a, PR #1558) titled 'packages: preserve architecture in primed stage packages' appears to address exactly this, so the issue should stay open pending verification that the fix is released in a snapcraft-supported craft-parts version.

Issue body
### Check existing issues
- [x] I've verified that this bug isn't described by any existing issues.
### Bug description
Look at `/snap/mesa-2404/current/snap/manifest.yaml`:
```
$ cat /snap/mesa-2404/current/snap/manifest.yaml | yq '.parts[] | .stage-packages' | sort -u | wc -l
140
$ cat /snap/mesa-2404/current/snap/manifest.yaml | yq '.primed-stage-packages' | sort -u | wc -l
64
```
Looking closer, the packages are listed without architecture.
### Steps to reproduce
With the attached YAML:
```
$ SNAPCRAFT_BUILD_INFO=1 snapcraft --verbose
$ unsquashfs base-cleanup_0.1_amd64.snap
$ cat squashfs-root/snap/manifest.yaml | yq '.parts[] | .stage-packages' | sort -u
- gcc-14-base:i386=14.2.0-4ubuntu2~24.04
- libc6:i386=2.39-0ubuntu8.6
- libgcc-s1:i386=14.2.0-4ubuntu2~24.04
- xz-utils=5.6.1+really5.4.5-1ubuntu0.2
$ cat squashfs-root/snap/manifest.yaml | yq '.primed-stage-packages' | sort -u
- gcc-14-base=14.2.0-4ubuntu2~24.04
