* report each hardlink as its own file when scanning images
image scans previously collapsed a set of hardlinks onto a single file, so only
one path per inode showed up in results. dir scans report every hardlink path,
which made image vs dir SBOMs of the same filesystem diverge (and produce
different SPDX `packageVerificationCode` values for packages that own hardlinked
files).
now both image resolvers (squash and all-layers) surface each hardlink at its
own path as a regular file bound to the target's content, matching dir scans.
user-facing impact:
- SBOMs for images containing hardlinks will list more `file` entries
- SPDX `packageVerificationCode` values change for affected packages, now
matching the equivalent `dir:` scan
- adds `file.NewVirtualLocationFromImage` to the public API
