BlackMark 76f4576fe0 pureboot: a loader in the staging slot is the staging copy — leave it there ...

The update flow's first step wrote the staging content over whatever the
staging slot held; with a loader running right there (programmed by hand
onto erased flash), that write met the copy's own running-slot guard on
the composed through-word and the tool stopped at its verify — although
the copy is exactly an installed staging copy, able to stream the new
resident like any other. The install is now skipped when the slot holds a
complete loader: its info block where every image carries it, matching
the device's byte for byte, and the slot unchanged since the update began
(the state file's snapshot) — so a resumed half-written install still
differs from its snapshot and takes the install path, which completes it.
pbrehome gains the staging-slot position (an older build at stage
streaming a newer resident in); the README's wrong "cannot re-home from
the staging slot" claim is corrected.
