Add gitlab-issue:// witness type, mirroring the existing github-issue:// witness. The protocol is identical (issue-based checkpoint request and cosignature exchange), adapted for GitLab APIs. New files: - docs/gitlab-issue-witness.md: scheme, protocol, triggering, setup guide - gitlab/cosign.gitlab-ci.yml: includable CI template for witness-side cosigning (POSIX sh on Alpine, path traversal guards, push-race retry, cleanup job with timestamp-filtered close) Modified files: - actions/checkpoint/action.yml: new gitlab-token input and gitlab-issue) case arm (create issue via POST /projects/:id/issues, poll for closure, extract cosig from issue notes) - actions/checkpoint/README.md: document gitlab-token input and usage - README.md: mention third witness type, CI template location - internal/policy/policy_test.go: TestPolicyGitLabIssueWitnessURL asserts gitlab-issue://gitlab.example.com/group/subgroup/my-witness is stored verbatim and verification works Verification: - go test passes on all pure-Go packages (internal/policy, internal/note, internal/gitutil, internal/witness) - YAML parses (python3 yaml.safe_load) - Shell scripts pass bash -n and dash -n - NOT yet tested against a live GitLab instance
