Classify the rename-blind changed-path list against direct Talos
sources and shared build inputs. This lets same-repository pull
requests skip the heavy build while removals, renames, and build
configuration changes still select it. Fork builds remain
unconditional.
Preserve the matchbox digest produced by a successful Talos build when
finalize overlays base-branch image references. When the job is
skipped, bootbox continues to receive the current base reference.
