Add playground auto-deploy

[PhilippGrulich]

Summary

Adds a root-owned deployment script and systemd timer for the Nautilus playground container.

What changed

• Added a revision-aware deploy script that fetches main, skips no-op runs, builds commit-tagged runner/API images, validates an isolated candidate, and rolls back on failed promotion.
• Added a systemd oneshot service and timer to run the deploy check every four hours with jitter.
• Added a plan note documenting the rollout contract and operational expectations.

Why

This keeps the playground aligned with upstream main without requiring manual redeploys.

Impact

• The live playground should pick up upstream changes automatically within about four hours.
• Failed promotions revert to the previous container instead of leaving the service down.
