Ship PR: credit-aware autonomous pull request readiness workflow. Use when the user asks to ship work, prepare a branch for review, create or update a PR, make CI green, clean up a branch before PR, or produce a PR a human can confidently merge. This skill may edit code, run checks, commit, push, create/update a PR, and iterate on CI, but it keeps Git ownership in the coordinator, delegates bounded work to cheaper host-native workers, uses review-code-dev v2 (Alibaba OCR delegation) as the only independent read-only review gate, waits for all visible latest-SHA CI to be green, runs capture-learning-tools report-only, and never merges.
