/**
 * Placeholder GitLab provider. Not implemented — every method throws so callers
 * fail loudly instead of silently no-op'ing on a real GitLab repo. Prior revisions
 * returned fake data / empty arrays, which masked configuration bugs (PR creation
 * "succeeded" but nothing happened upstream).
 *
 * To implement, map each method to the GitLab REST API:
 *   https://docs.gitlab.com/ee/api/merge_requests.html
 *   https://docs.gitlab.com/ee/api/branches.html
 *   https://docs.gitlab.com/ee/api/issues.html
