* feat: reconcile systemd unit files on upgrade Unit files were written once at install time by install_systemd() in scripts/setup.sh and never re-asserted. A node upgraded by swapping the spx binary kept whatever units it was installed with, so any fix that lives in a unit rather than in code never reached it. This is not theoretical. A node whose spinifex-viperblock.service predates KillMode=process defaults to KillMode=control-group, so on a target stop TimeoutStopSec expires mid-flush and systemd cgroup-SIGKILLs every nbdkit while guest QEMU survives in the daemon's own cgroup: the guest keeps running with no storage path. Units are now stamped with a spinifex-unit-version marker, embedded in the binary via a generated file, and reconciled by spx admin upgrade. Missing or version-stale units are replaced after a timestamped backup; a unit at the current version whose content differs is reported as operator-modified and never overwritten. Drop-ins under <unit>.d are untouched, so systemctl edit overrides survive. Nothing is restarted. A daemon-reload is enough for KillMode and TimeoutStopSec to apply to the next stop, so drift is corrected without disturbing a running guest. Adds --dry-run, --units-only and --skip-units to spx admin upgrade. * test: cover systemd reconcile error paths and the admin upgrade CLI flow Diff coverage on the unit-migration PR sat at 45.8%, below the 60% gate. Adds tests for reconcile.go's error/edge paths (unreadable unit, backup and write failures, daemon-reload failure, malformed version markers, downgrade-is-conflict) and drives admin_upgrade.go's CLI flow directly via an injectable exit and a decision matrix extracted into validateUpgradeFlags/upgradeSummary for testability.
