Greptile Summary

Updates the pinned UKCI kernel sources to newer stable and release-candidate revisions.

• Advances the 6.1, 6.6, 6.12, and 6.18 LTS kernel tags and hashes.
• Advances Linux 7.1 and the 7.2 release candidate, keeping their explicit versions synchronized with their tags.

Confidence Score: 5/5

The PR appears safe to merge.

The updated tags, explicit versions, and hashes preserve the source-specific formats used to construct each UKCI kernel fetch, and no blocking or non-blocking issue remains.

Important Files Changed

Filename	Overview
nix/ukci.nix	Updates six kernel source pins and their fixed-output hashes consistently; no actionable defect was identified.
