feat(ci): rewrite all 4 workflows matching htpasswd standard pattern

- pr.yaml: PR checks (hadolint + build-test) on PRs to main
- main.yaml: lint → test → build → auto-tag on push to main
- tag.yaml: lint → test → build-push with tag-based Docker metadata
- cron.yaml: nightly rebuild (0 0 * * *) with latest semver tag

Adapted from perso/htpasswd template with:
- Image: jcabillot/docker-duplicacy
- Git URL: scm.cabillot.eu/perso/docker-duplicacy.git
- RELEASE_BRANCHES: main
- Cron schedule: '0 0 * * *' (from original cron.yaml)
- Secret: GITHUB_TOKEN (existing)
