After the 26.19 → 26.20 self-update the bench had furtka-welcome.timer
linked + enabled but inactive (dead): enable only arms a timer for the
next boot. The link also pointed at /opt/furtka/versions/<ver>/ instead
of /opt/furtka/current/, unlike the installer-created links, so it would
have stopped following later updates and rollbacks. Link via current,
enable, start.
Adds docs/hardware-test-2026-08.md (timeline, five findings with root
causes / fixes / validation status, what worked, open items) and a
'Real hardware' section in iso/README.md.
