Release gate skill for Codex. Use when review and QA evidence already exist and the main task is to validate tests, coverage, commit hygiene, branch strategy, and safe push behavior before merge or deployment; triggers include ship, release, push, merge, deploy, and handoff-before-merge requests. Prefer `mstack-plan` for design-only work, `mstack-qa` for verification-only work, and `mstack-pipeline` for one-shot end-to-end workflows.
