chore: release v0.20.2

Closing OpsLog dropped the CAT, whose frequency went to 0; the auto-control
read that as out of range and switched the relay OFF, then ON again at the next
launch. Now a rule is skipped entirely when the frequency/band is unknown (CAT
off), so relays keep their state across a close. And on the first evaluation
after launch/save it reads the boards' LIVE state and only switches a relay
that isn't already in the wanted position — no more clunk when it's already
correct.
