Port .gitea/pull_request_template.md to .gitlab/merge_request_templates/ Default.md so new GitLab MRs surface the same structured prompt once Phase 2 lands the pipeline and developers start opening MRs. Two content adjustments vs the Gitea original: - PR -> MR in the comment header (GitLab terminology). - Fixed a stale ref to docs/development.md "section 5" (Observability dev-loop); the Conventional Commits convention is in section 7. Phase 1 ships repo-side artefacts only; ops bootstrap (mirror push, groups, branch protection, bot signing keys, Renovate endpoint reconfig) happens on vm-gitlab outside this PR per ADR-0028 section 'Migration sequence'.
