feat: add pre-cache timer, force_pull, and Docker socket options to runner config

- Add force_pull: false (explicit default) to runner config template
- Add options field to mount host rootless Docker socket as /run/host-docker.sock
  so CI containers use the host daemon (full disk) instead of nested DinD
- Add valid_volumes list for the socket mount targets
- Add pre_cache.yml task with systemd timer that pre-pulls CI images every 6h
  to prevent thundering-herd registry timeouts when all runners start jobs
- Add docker-pull-images.service.j2 and docker-pull-images.timer.j2 templates
- Bump devx from v0.50.0 to v0.50.1 (includes start_docker.py host socket fix)

Closes GRM-162
