The U2 leg of planning:host-update-from-web-console.md. A new dep-free root helper
(crates/pf-update) runs the distro package manager against the INSTALLED punktfunk
packages — apt (index refresh scoped to our list when present), dnf, rpm-ostree
(single-transaction re-resolve, reported staged), sysext (the proven signed-feed
updater), pacman only behind the explicit PACMAN_FULL_SYSUPGRADE opt-in — then the
run-the-binary gate, then a root-written result record. Zero attacker-influenceable
parameters end to end: fixed ExecStart oneshot (punktfunk-update.service), polkit rule
scoped to that one unit's start verb for the shipped-EMPTY punktfunk-update group
(joining it is the auditable opt-in; every postinst creates it, none populate it).
The host starts the unit, interprets the record (staged / nothing-newer-yet / changed),
and crosses its own restart on the same intent/reconcile machinery as the Windows leg.
Status now reports staged results and the opt-in hint.
