Viktor Barzin 42961a5f58 [registry] fix-broken-blobs.sh — check revision-link, not blob data
The original index-child scan checked if the child's blob data file
existed under /blobs/sha256/<child>/data. That's wrong in a subtle
way: registry:2 serves a per-repo manifest via the link file at
<repo>/_manifests/revisions/sha256/<child-digest>/link, NOT by blob
presence. When cleanup-tags.sh rmtrees a tag, the per-repo revision
links for its index's children also disappear — but the blob data
survives (GC owns that, and runs weekly). Result: blob present,
link absent, API 404 on HEAD — the exact 2026-04-19 failure mode.

Live proof: the registry-integrity-probe CronJob just found 38 real
orphan children (including 98f718c8 from the original incident) while
the previous fix-broken-blobs.sh scan reported 0. After the fix, both
tools agree. The probe had been authoritative all along; the scan was
a false-negative because it was asking the wrong question.

Post-mortem updated to reflect the true mechanism (link-file absence,
not blob deletion).
