Benjamin D. Smith d67e0bd168 feat(ship): add Step 1.5 pr-prep gate before merge + tests ... `/ship` now invokes `/pr-prep --base $BASE_BRANCH --json` with `GSTACK_FROM_SHIP=1` before any of: merge base branch, run tests, version bump, push. If pr-prep returns EXACT_DUP (exit 1), ship aborts with a pinpoint message naming the upstream PR + resolution paths (close mine / cherry-pick unique parts / coordinate + retry with `--skip-pr-prep`). Skip conditions: - No upstream remote configured (solo-repo case) - `--skip-pr-prep` flag (override) - pr-prep skill not installed (older gstack — stderr warn + continue) SIBLING / OVERLAP / CLEAN buckets do NOT block. The JSON report is written to `/tmp/ship-pr-prep.json` so Step 19 (PR body assembly) can render upstream context as a collapsed section. Helps reviewers triage faster. Catches the real bug class motivating the new skill: contributor pushes branch with N commits, M of N duplicate already-open upstream work, reviewer closes the dups, branch cleanup churn. /ship now fails fast before any test run wastes time on a doomed branch.		2026-05-26 00:09:08 +10:00
