pideploy v1.1.0

Added

• Remote mode — set runner_host=you@host on a dev machine and pideploy init
  registers the runner on the host over SSH (via the new host-side register
  command), then only scaffolds + pushes locally. So you can onboard repos to your
  Pi from your laptop — no Docker or systemd needed there. Needs SSH to the host
  (e.g. Tailscale SSH) and pideploy installed there. The generated workflow uses the
  host-resolved runner label; --serve in remote mode prints the host-side command.
• pideploy register <owner/repo> — host-side: enroll a self-hosted runner for a
  repo and assign/record its port (returns runner/port/label/registered).
