Replace pi's nightly system.autoUpgrade with comin, a pull-based GitOps deployer. comin polls the `deploy` ref every ~60s and switches to nixosConfigurations.pi. A new CI `deploy` job fast-forwards `deploy` to each merged commit only after all-builds passes, so pi never deploys raw main and converges within a minute of CI going green.

Candidate C (comin-based gated pull) — a third alternative to A (#483) and B (#482); only one of the three merges. Same shape as A (pi pulls a CI-gated
