v0.9.29

Fixed

• Self-hosted GitLab on non-default ports / plain HTTP rejected: Client::new rejected any MR URL whose host contained : (killing every explicit-port URL, e.g. http://gitlab.internal:8929/…) and always built the API base with hardcoded https:// (killing plain-HTTP internal installs). URL parsing is now extracted into Client::parse_mr_url → ParsedMrUrl { scheme, host, project_path, mr_iid }; the URL's own scheme is honored, and an optional :port (digits, 1–65535) is accepted. Hardening kept: userinfo (@), .., empty host, bad ports, and IPv6 literals are rejected with clear messages. Benefits every entry point — REST gitlab_mr reviews, CLI review/ask/describe/improve, and GitLabProvider. (src/git_provider/gitlab/client.rs)
• Invalid MR URLs now fail fast with 422 at enqueue instead of 202-then-async-failure: submit_review and rerun_review validate the gitlab_mr URL synchronously and return 422 invalid gitlab_mr url: … without creating a task. (src/server/api/review/handlers.rs)
