revert(gitlab): drop draft-skip rules + stderr tail-60 capture

Removes two GitLab-only behaviours that don't exist in the GitHub action:

- Draft/WIP `rules: when: never` block. GitHub leaves draft handling to the user's workflow `if: ... draft == false` condition and doesn't bake it into the action. Customers who want to skip drafts can add the same condition to their own .gitlab-ci.yml.
- Stderr tail-60 capture into droid-error.txt. GitHub uses core.setFailed(error.message) which surfaces in the Actions run summary, not in the PR comment body — the comment just shows an actionFailed flag. Revert to the plain "droid exec pass N failed" message for parity.
