Self-hosted GitLab environments lack ENV0_PR_SOURCE_REPOSITORY and GITLAB_TOKEN. This adds fallbacks so the plugin works out of the box: - Use ENV0_TEMPLATE_REPOSITORY to derive the GitLab API URL when ENV0_PR_SOURCE_REPOSITORY is unavailable - Accept ENV0_VCS_ACCESS_TOKEN as a fallback for GITLAB_TOKEN - Construct a stable MR URL as --ticket-link so Overmind deduplicates changes across multiple plans for the same merge request - Strip trailing .git from repository URLs Made-with: Cursor
