feat: dual-registry publishing (GHCR + Docker Hub)

Publishes container images to both registries:
- GHCR: ghcr.io/host-uk/core-images:{image} (org access)
- Docker Hub: lthn/{image}:{version} (public distribution)

Changes:
- Add Docker Hub login step (requires DOCKERHUB_USERNAME, DOCKERHUB_TOKEN secrets)
- Update metadata to generate tags for both registries
- Enable dev branch builds
- Fix LinuxKit build to use linuxkit directly (not core CLI)
- Use correct double-dash flags for linuxkit

Naming:
- developer -> ghcr.io/host-uk/core-images:developer + lthn/core-dev:latest
- server-php -> ghcr.io/host-uk/core-images:server-php + lthn/server-php:latest

Closes #1
